Thank you for the speedy reply. On the page you were kind enough to link to, in the grey box at the top, it says "For taxable years beginning January 1, 2020, a pass-through entity that has paid withholding on behalf of a nonresident owner or has been withheld upon must use Form 592-PTE, Pass-Through Entity Annual Withholding Return."
I am using Proseries Professional. I was hoping that Proseries e-filed it. On many forms PS includes, the form is often notated that it needs to be paper-filed, and includes the address. This form had no such notation, which is what confused me.
The form PS produces also says it is for taxable year 2021, which also doesn't make sense to me since we're just calculating the 2020 returns now.
