I received a 1099-Misc for the state stimulus, where to I enter it? Under the 1099-MISC it asks for who and I can only choose one person not both, we are both on it.

It doesn't matter who you pick.

Enter the CA Middle Class Tax Rebate on a 1099Misc and put the amount in box 3. It will show up as Other Income on Schedule 1 line 8z which flows to 1040 line 8.

Go to Federal > Wages & Income, you might need to continue though the general screens.
When you come to the Wages - Your Income screen click on Add Income or
scroll down to Other Common Income, then 1099Misc.
Put the amount in box 3 and follow the prompts.
On the page with a long list of reasons pick None of these apply -Continue.
Say No it did not involve work -Continue
You got it in 2022 -Continue
