IRS letter requires E-filing this year. Their website directed me to a list of links, from which I chose ito.intuit.com and signed up and paid for a return. But this seems to be for a professional accounting business to use Intuit. I just want to do my 990PF using Intuit's system and efile through it. Doesn't seem like I should need an EFIN for it but I'm lost on what to do.
