Thank you @MarilynG1 for the quick response! The email says:
R0000-902-01 - Taxpayer TIN in the Return Header must not be the same as a TIN of a previously accepted electronic return for the return type and tax period indicated in the tax return.
I tried filing a second extension and received the same error. The strange thing is that I haven't completed the electronic return yet... at least that what TurboTax tells me "We notice you haven't e-filed any of your returns".
I am getting a refund so it sounds like I don't need to file an extension, which is good to know.
Any thoughts on how I can check if a return has already been filed under my SS#? I tried the IRS site, but it requires I know the exact amount of the refund/amount due, which of course I don't since I don't think I've filed one yet.
