Deductions & credits

2020 Turbotax interview did not ask if I itemized deductions in 2018.  I took the standard deduction in 2018.  I received a state refund in 2020 for filing an amended state tax return for 2018 as reported to me on 2020 1099-G.  Turbotax is reporting that this 2018 refund is taxable and included in Schedule 1, Part I, Line 1.  Should I override that entry and change it to $0?  It seems that Turbotax should ask me whether I used the standard deduction in 2018 and complete the Schedule 1, Line 1 properly instead of making me override its calculation.  Please confirm this is the solution to this error in the program. Thank you.
