Your Maryland 504 K-1 information would be reported on your Maryland non-resident return, so it does not get entered on your federal tax return (only the 1041 K-1 does). TurboTax will pass along the information to your Maryland return from the Federal 1041 K-1 form that was entered. Then, during the interview process of the Maryland non-resident return, you should be asked if you need to make any adjustments (additions to income or deductions such as in sections 3 and 4 of the 504 K-1) to your K-1 form which would be reflected on the 504 K-1.
