What is the '"shield" you have, or is it a UNO controller?
What is your application, what are you trying to do?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you tell us your electronics, programming, Arduino, hardware experience?
Thanks.. Tom.. :)
I have no idea what shield it is, that's what I got.
I'm trying to do a parking lot
this is my first project/anything relating to programing or Arduino.

Are you using bluetooth or other communications? If not, you can use those pins. Only thing to be aware of is that you might loose the option to upload code at the moment that something is connected to those pins; simple to solve by disconnecting anything that is connected to those pins before you upload.
If you use the RX pin for other purposes, you should still be able to use the TX pin for debugging to serial monitor; but I have never tried it.
What else comes in that kit that you have. Something like 74HC595? That will give you 8 outputs at the expense of 3 pins (probably will not help you in this case). Maybe a multiplexer (something like 4052 or 4067).
I'm not using any communication (if LCD is communication so yes)
I don't really know what is in the kit I just got it because the school made me without telling me anything.
Also I don't need the Blue color in the LCD can I use it (digitalpin 11) as another pin?
I guess that this relates to https://forum.arduino.cc/index.php?topic=476404.0.
Are you using the shield (that big red piece)? Or are you running without it.
For others: Pictures related to this
yes it my Arduino and my post. the Arduino is connected to this red thing.
