TurboTax has filled Maryland 2021 form 502, line 17 with 4700. When I click on the cell in the form, there is no indication where this amount comes from or ability to change it.
Line 17 deals with adjustments to deductions if itemizing. I am not itemizing on our federal return and the Standard Deduction Method box at the top of Maryland 502 line 17 is properly checked, so all of line 17 should be blank or zero. Indeed, lines 17a and 17b are 0, but then there is the mysterious 4700 in the final line 17.
