State tax filing

Yes, I downloaded the Partnerships for Maryland tax return. From the link you gave me, I found 2 unsupported files.
Form EL101B Income Tax Declaration for Business Electronic Filing available but unsupported.

And
Form EL101B Income Tax Payment Voucher for Business Electronic Filers available but unsupported.

I e-files 2 other Partnerships companies with no problems, TT did not ask me to use form EL102B. The only different with this company, it is a short year filing, and also last year filing since it was sold. The short year is 1/1/2023 to 2/16/2023. For some reason TT business gave me due date to file by 5/15/2023, not 4/15/2024 as expected. It is exactly 3 moths after the end of the short year. I of course could not have filed in 2023.
thank you for your help.
