K1 Trust nonresident

[Popgam]

Amended my tax forms because received a K1 form 1041.

After adding the K1 to income on the federal 1040x, the headline showed I owed 397. After printing and reviewing the forms, their is a 1040 SR, that has a signature block and /or but it has an owing amount on line 37 of 4713 and a tax penalty of 168. So I'm wondering what this form is.

If you are a non resident alien, you would need to file a 1040NR.  If you already filed a 1040SR, you could go to Sprintax.com for help with filing your Non Resident return.  The rules for nonresident aliens are different than the rules for US citizens and US resident aliens.
