Shortage of GPIO pins

Hello! I'm currently working on a project where im "building" an egg cooker. Here i am using a Raspberry Pi 4B which has the 2x20 GPIO Pins. In regard to my project i have bought three things. A responsive screen, solid state relay and temperature sensor. DS18B20 Digital Temperature Sensor - https://dk.rs-online.com/web/p/sensor-udvikling/2049893?cm_mmc=DK-PLA-DS3A-_-google-_-CSS_DK_DK_Raspberry_Pi_%26_Arduino_%26_ROCK_og_udviklingsværktøj_Whoop-_-(DK:Whoop!)+Sensor-udvikling-_-2049893&matchtype=&pla-300807621014&gclid=Cj0KCQjwtsCgBhDEARIsAE7RYh2aFs4krnS_mm63JSevVczBqeDqywP0413sCPVfhi3_hr5EVQhZ-w4aAmdrEALw_wcB&gclsrc=aw.ds Currently i have this wired to a breadboard and then two wires from the breadboard going into GND and 3.3V on the GPIO pins. Solid state relay Connected to a GPIO pin and GND 4DPI-32 MK2 - https://dk.rs-online.com/web/p/raspberry-pi-skaerme/9094105 As i was able to read and see this screen uses/clicks on all of the GPIO pins, which i wouldn't be able to because as i explained i am using some of the GPIO pins for my solid state relay and temperature sensor. Is there any way you guys would know a way to workaround this?

I will look at that. Thank you

Your welcome and don't "cross post" in the future. Post in one place, wait a couple of days and then post on the next place if you don't get any responce

Of course, i will remember that. Just one last question. This serves kind of the same purpose right? I would be able to put the screen on the extended GPIO pins and then my sensors and so on in the "blues"? https ://www.digikey.dk/da/products/detail/seeed-technology-co.,-ltd/114992565/13635853

YES kind off

And a tip, you can shorten the URLs by trim away everything after the question mark (?), like this https ://www.digikey.dk/da/products/detail/seeed-technology-co.,-ltd/114992565/13635853
