Current Sensor Acs712 with LCD SainSmart I2C 20x4

I want to create a live current meter of a stepper motor for monitoring purposes.

The current sensor I am using is Acs712-20 with 20Amps monitoring capability.
The LCD I am using is a 20x4 SainSmart with a lcd2004 backpack.

I managed to drive the screen and I managed to drive the current meter and monitor the current from the Serial Monitor.

Now I want to:

-Feed the Current Values from the ACS712 to the SainSmart LCD 20x4.
-Have a refresh rate of 1000ms on the LCD Screen of the data that ACS712 gives out.

What I have done until now:
-I have given the analog.Read to the LCD but it gives out only the first column readings of the acs712 which is the Raw Value. No use for me.

Problems:
-I want the value of Amps to appear in the LCD
-To even update the rawValue, I have to reset the arduino, and it does not refresh as the serial monitor does.

-My wiring:

--LCD to Arduino UNO
VCC to +5V
GND to GND
SDA to A4
SCL to A5

---ACS712 to Arduino UNO
VCC to +5V
GND to GND
OUT to A1
And the sensor pins in series with a load

Serial Monitor Data
Raw Value = 504 mV = 2460.937 Amps = -0.391
Raw Value = 503 mV = 2456.055 Amps = -0.439
Raw Value = 503 mV = 2456.055 Amps = -0.439
Raw Value = 503 mV = 2456.055 Amps = -0.439

const int analogIn = A1;
int mVperAmp = 100; // use 100 for 20A Module and 66 for 30A Module

void setup()
{
  lcd.begin (20,4);
  
  // Switch on the backlight
  lcd.setBacklightPin(BACKLIGHT_PIN,POSITIVE);
  lcd.setBacklight(HIGH);

  int sensorValue = A1;
  sensorValue = analogRead(A1);      // read sensorOne value.


  // Position cursor and write some text
  lcd.home ();                   // go to the first line, first character
  lcd.print("READING");  
  lcd.setCursor ( 0, 1 );        // go to the 2nd line
  lcd.print("A1");
  lcd.setCursor ( 0, 2 );        // go to the third line
  lcd.print(sensorValue);

 
 Serial.begin(9600);
}

void loop(){
 
 RawValue = analogRead(analogIn);
 Voltage = (RawValue / 1024.0) * 5000; // Gets you mV
 Amps = ((Voltage - ACSoffset) / mVperAmp);
 
 
 Serial.print("Raw Value = " ); // shows pre-scaled value 
 Serial.print(RawValue); 
 Serial.print("\t mV = "); // shows the voltage measured 
 Serial.print(Voltage,3); // the '3' after voltage allows you to display 3 digits after decimal point
 Serial.print("\t Amps = "); // shows the voltage measured 
 Serial.println(Amps,3); // the '3' after voltage allows you to display 3 digits after decimal point
 delay(1000); 
 
}

move lcd.print from setup to loop

And how will I get the current readings from the sensor and not the raw data?

Your datasheet shows the graph "Output Voltage versus Sensed Current"
There are 3 different 712s -> 5A 20A 30A typical 185mV/A , 100mV/A and 66 mV/A

define my712 185.0 // or other

Calculate voltage (with a 5V reference, U'll have 5/1023 v/step)
=>float millievolt = (analog reading - 511) * 4.8876; // factor is 5000/1023 for millivolt result
=> float current = millivolt / my712;

print the current to LCD
