Request Tax Returns transcripts - form 4506t

Hi,

I'm currently in the process of filling out form 4506t to request my tax return transcripts, and I have a couple of questions:

1. I filed jointly from 2016 to 2021. Should I include my ex-husband's name in the form for those years?

2. The form provides space for only four years. Can I include two forms in one envelope?

Thanks in advance.
