Maryland Form 500DM -

You might have to enter something in the State section.

Contact Support if you cannot resolve this by tomorrow.

How do I contact TurboTax? (intuit.com)

I haven't been able to find anyplace to enter the net decoupling modification on my MD taxes.  It should appear on form 500DM but that form hasn't been generated by TT.  I have manually entered the figure but, even though the figure appears on the form, TT doesn't include the addition in their calculations

I am having the same problem and so are other shareholders in my S Corp. There is no place in TurboTax to enter the Net Decoupling Modification from the Maryland K-1. You can pull in a MD Form 500DM in the forms section and insert the figure in that form but, as noted in another message, that information does not flow to the tax return.
