I ran into what appears to be a TurboTax bug on Maryland returns while using the Desktop version of Turbotax Home & Business for Mac users for 2025 returns.
The Problem:
When I imported my spouse’s W-2, the Maryland state tax withheld (W-2, Box 17) did not populate into the Maryland state return, even though the W-2 appeared correct in the federal section. As a result, Maryland withholding showed as missing on Line 41 of Maryland Form 502. This caused the calculated Maryland tax due to be significantly overstated, since the state withholding from the W-2 was not included as a deduction on the Maryland return.
Note: It is unclear if this issue affects other state returns. Has anyone else noticed this?
Solution:
Deleting the imported W-2 and re-entering it manually immediately fixed the issue. Line 41 withholding then populated correctly on Form 502. This appears to be an import/mapping issue specific to the Maryland return. In my case this resulted in an incorrect balance due of nearly $10,000. It was quite a relief to find the solution! I’m posting here so other users are aware and in case TurboTax can flag or investigate it.
