Turbotax has included MD Form 510D with my tax return. From the instructions, it appears that this form is not needed. How do I know for sure?

Form 510D is used to pay in estimated tax for nonresident members of the partnership. Since you don't have any non-resident partners, you do not need to file the form. You may need to go back through your entries to determine if you indicated that you had non-resident partners.

Thanks for the reply. I not only checked all entries, Form 510D itself recognizes all the income attributable to residents only on Line 6. Taxable income for non-residents on Line 1 is zero. I also answered the question about whether we (the PTE S-Corp company) want to pay estimated taxes for FY22, and we we said no. Even then, Turbo Tax generated this form, populated it with resident income, and calculated estimated taxes due. I think it is a bug in Turbo Tax. What should I do now?

You can try deleting the form. Use the Forms menu option to bring the form up, then see if there is an option on the bottom of the form to delete it.

Also, the form is for paying estimated taxes, so you can simply not pay the tax it says is due and there won't be any penalties associated with it and you won't get any notice from the state requesting payment. 

Thanks. I tried deleting Form510D using Delete Form button but the form was not deleted. I also found a weird problem that there is a difference between Form 510 when I see it using Form view compared to when I see it as a pdf view. The Form view is correct, the pdf view is not. It looks like a bug in the software and my MD return is completely incorrect - incorrect Form 510 and unnecessary Form 510D. I don't think that in its current form, I can file it electronically! Any suggestions that I can try short of printing it, correcting it by hand, and mailing it physically?

Some question you have answered in the process of completing the return is generating form 510D.  Otherwise you would be able to delete it.  If you can't find what is generating it I suggest deleting the entire MD return and starting over - paying careful attention to questions regarding estimated payments.

Before completing it is also a good idea to clear your cache and cookies.
