How to find if IRS accepted return?

Filed for my SO on Thursday morning using Free Fillable Forms. Got email that return was queued for transmission immediately. More than 48 hours have pasted and still no acceptance (or rejection) email. Checked status of the E File on Free Fillable Forms and it says IRS accepted it, but in all the years I’ve used this e-file option I never failed to receive an email confirming acceptance before.

She had a balance due (which she plans to pay later via IRS Direct) so Find My Refund can’t help us. Any other way to confirm acceptance of the return.

Email delivery isn’t guaranteed. I assume you have checked your Spam folder. Some files fail in transmission and some are eliminated by the email provider’s spam and virus filters which occasionally misidentifies email as dangerous.

It is early in the tax filing season. If she has an IRS account, it should show up when processed.
