Looking at the screenshots you shared, it appears you're taking the standard deduction rather than itemizing, and so you wouldn't be able to deduct the MA vehicle excise tax even though it qualifies for that purpose. If your itemized deductions reported on Schedule A (such as Line 5 State and Local Tax Payments) are not higher in sum than the standard deduction, then you should continue to take the standard deduction, and not worry about entering small amounts that are for itemizers.
TurboTax will switch automatically between the Standard Deduction and Itemized Deductions based on your entries, so it is important to enter all your data if you're unsure if you meet the threshold.
This screen "2024 and 2025 Deductions & Credits" is a summary of items entered, not items that are necessarily deductible for your tax return. Alimony is non-deductible federally but is allowable for your state, for example. You should should select Forms and view Form 1040 and its schedules under Forms in My Return on the left side, to see which items are actually being applied on your tax return bottom line.
Do you need this payment to be entered so that you meet the threshold for claiming itemized deductions? If so, we can begin to troubleshoot the data entry issue.
