I recently e-filed an amended federal return (1040X) for the tax year 2020, and am in the process of filing an amended return with the state of CA. In the Federal Return instructions Turbotax provided me, it says that I should include a copy of [any form or schedule that changed] with my federal amended return. However, since I e-filed the federal amended return through Turbotax, the electronically filed return didn't include the 1099-R form that was changed. Do I need to send the changed 1099-R to the IRS? If so, how should I do it? I'm concerned about them being able to match up that 1 form with my amended return. Thanks
