In Colorado, the federal exclusion of the first $10,200 of unemployment benefits is still taxable for 2020. Is this amount added back as an adj. for the state return?

Yes, Colorado is taxing unemployment in full so you must add back the federal exclusion.

How do you do that in filing?

I get to the screen that says federal -10200.  What do I put in for colorado then the next screen says federal 10200 what do I put in for colorado

TurboTax will take care of this for you.

Yea but I don't know what numbers I need to put in those two screens for the unemployment 

I'm not sure which screens you are referring to.  You will enter your 1099-G (unemployment) form in the federal portion of the return and it will be carried over to your state return.

Assuming you live in Colorado, you will enter the amount of unemployment you received in the Colorado boxes here.  If the amount of unemployment received was greater than $10,200, you will enter the maximum amount of $10,200.

I do not live in colorado but earned unemployment in colorado   so I can enter -10200 in for colorado on screen 1 and then 10200 on screen number 2 since that affects colorado 

I just dont know what i need to enter on the above 2 screens

Can i assume i enter -10200 and 10200 on those screens respectively?

Yes, because that amount is attributed to Colorado.
