How to attach document to efile return using 2022 TurboTax. I have a need to attach a PDF file to my tax return. How can I attach the PDF file when e-file my return ?

you probably can't attach it because it is nonstandard.  the tax program has no way to understand what's on that document and covert the letters and numbers into 0 and 1s for transmission. you'll have to mail your return. 

Thanks for reply.  That's a bummer and a hassle for me.  Don't get why TurboTax and IRS can't enable uploads of necessary documents in this day and age, smh
