I took an early withdrawal from my IRA and I am exempt from early withdrawal penalties due to permanent and total disability. Turbo Tax has automatically included my form 5329 to accompany my filing with the correct indication of disability. Most information I can find says I need to also include proof of my disability with my tax return filing. I have the proof but don't know how to add it to my Turbo Tax e-file. How do I add my proof of permanent and total disability to my Turbo Tax e-file to accompany my form 5329 to avoid early withdrawal penalties on my IRA withdrawal?
There is no way to add such documentation in TurboTax. Those instructions are probably assuming that you are printing and mailing your return. Don't do that.
Instead, just e-file your return with TurboTax, then, if the IRS is really interested in documentation, they will write you a letter asking for it. The IRS is swimming in paper, so they will ask for it only if they really want it.
