Great question! The instructions would be the best place to identify whether you still need for file for the specific returns you have. Here's the link to the instructions: https://revenue.alabama.gov/wp-content/uploads/2020/12/20fptecpteck1_inst.pdf
If you are having trouble triggering the form and you have set your partners as non-resident, I would recommend you contact our support so that they can help you with the input for the return.
You can choose the Live Chat link from the left hand column for support.
