MX State ID

[Ediepie]

TurboTax 2025 Deluxe offline program accepts proper 1099-INT multi-state ID input to MX and then flags it for correction in the Federal error check review.  The totals from eight states are correct and were entered individually with correct state IDs, but TurboTax reset the total form to MX and then wants it corrected.  It appears that the two events were not coordinated in the application.

Are you entering tax exempt municipal bond interest?  You should just need to allocate the interest between your resident state(s) and the rest to multiple states.  I'm not sure what you mean by setting the multi state ID to MX - did you mean multiple states?

If you could reply back with additional details about whether this is municipal bond interest and to what is meant by MX plus any other relevant information about this situation, that will help us to better help you.
