I'm so frustrated because I need to report one weird thing in an otherwise vanilla filing for Tax Year 2023.
Can I file electronically, if I also mail one form which turbotax does not support?
In another question, this user was asking about mailing in a form 709.
@taxpayer252342 Mailing in the form 709 does not affect your e-filing of your actual 2023 Income Tax return. They aren't linked.
What form do you need to mail? What special thing do you need to report?
