State tax filing

Thank you, now I see what you mean; have you fully completed the State Taxes interview screens for Maryland income and questions, including the MD 510 K-1 questions that start on the screen below? That's where you enter your state modifications, subtractions, and credits (etc.) received on the state K-1 to flow into the appropriate sections on the personal state tax return Form 502:

Select yes on the above screen if you have not already done so to add in your MD decoupling items, and then double check Form 500DM for the correct appearance of Part C Line 9. 

If you have already completed this section in full, we can begin a software investigation for issues with the current year MD 500DM. 

Note: Technical Bulletin 38 guidance for applying MD depreciation decoupling modifications in specific taxpayer situations has not yet been updated to include TY2025 changes from OBBBA or related changes to state law, which may pose a delay in troubleshooting.
