I’m applying for a loan, and they are requesting a cover letter from TurboTax. Where can I find this?

A cover letter saying what?  There is an instruction sheet but Turbo Tax is a Self Prepared Return and you don't get anything from Turbo Tax except an email saying it was accepted or rejected.

you could show them the email saying the IRS Accepted your return or print out your efile status here
