Deductions & credits

TT MUST FIX THIS GLITCH! Nearly all customers are having this issue. I have the same issue. Married filing jointly.  Cash charitable contributions with receipts greater than $600.  Standard deduction taken. Easy calculation: my Line 12b deductible amount is clearly $600.  But TT figures $300. Clearly a programming error that needs to be fixed. Same rule in 2020, except maximum deduction was $300.  Seemed to work fine for 2020. Why the huge problem for 2021? I cannot file an accurate 2021 return using TT. That should concern TT.
