I prepared my own individual tax return in Proconnect tax and forgot to file the Alabama PPT for my LLC along with it. I know I shouldn't have forgotten but things got so busy that I only filed the Schedule C and forgot about my own PPT.

I am trying to now go in and file the PPT separately but I am not sure if it is possible - it is definitely not working with my individual return as it has already been filed. I am currently trying to file it by creating a separate business tax return in Proconnect, but I do not see an option to only file a PPT.

Is my only option going to be mailing this in or does anyone have any suggestions?
