If I am being told to check this entry and it says State Tax Refund Worksheet Item Q Line 2 what do I put in there?

At the Analysis section and at the Check this Entry on Schedule A, Line Q. I don’t have a schedule A from my 2020 taxes, but I did receive a Maryland state refund. Do I enter the amount of the refund here, sans a schedule A?

If you don't have a Schedule A from your 2020 return, just enter $0 here.

Per Expert @JulieS:

"This error refers to the amount on line 5c of your Schedule A for the prior year, which is state and local personal property taxes. That is usually the deductible amount of your vehicle registration fees. 

If you did not itemize, you can enter 0. If you did itemize, just check your Schedule A from the prior year and fill in the number you had on line 5c."
