My only income is SS and a state pension. Same for many years. My tax due tripled this year. Usually around $250, this year $780. How could this be?

No state tax. Only federal.

Since SS is not taxable on the state return  your pension must have increased or the state withholding went down.  Check your entries for any missing decimal points or extra digits in the amounts.  Maybe delete your 1099R and enter it again manually.  That usually clears something out and fixes it.

Oh you said for Federal not state.  Then check your SS too.  Check if any of your SS is taxable on 1040 line 6b.  Compare your return with your 2022 return line by line to see what's different.
