Is there a direct replacement (pin for pin) for the elcheapo 1.44”TFT screens? I have a project that uses a 1.44 TFT screen but I find the screen a bit too small. I have tried to use a larger screen and changing the TFT driver with no luck.

Go on. Post a link to the screen you are talking about.
Yes, the common Red 3.3V SPI screens come in 128x128, 128x160, 176x220, 240x320, 320x480.
They all have the same basic pinout. 240x320 and 320x480 have a separate TFT_MISO pin.
Most have a (monster) SD Card socket.
You can often use the same library for ILI9163, ST7735, ILI9225, ILI9341, ILI9488 controllers

This is the one I am using.
I have only tried a QVGA 2.2 TFT SPI 240*320 same pinouts as the 1.44” but there is 1 extra pin labeled SDO(MISO)

Make sure that you line up the pins to match VCC, GND, CS, ... and leave MISO n.c.
There are plenty of ILI9341 libraries. Very few of them use MISO.
Make sure that you use 3.3V GPIO logic signals with the ILI9341. It will not work with 5V logic. You will damage the ILI9341 with 5V logic.
The ST7735 or ILI9163 on your 128x128 display also needs 3.3V logic but is more forgiving.

Thanks for the info. I am not a programmer and just getting started, well 2years on and off. I got the QVGA 2.2 SPI TFT working by making voltage divider with resistors. Works a treat. Thanks again
