My efile got rejected because AGI was incorrect. I tried to get my AGI online apparently my info was incorrect. I mailed my return and not that is lost. What do I do?

IRS is way behind processing paper returns.

IRS says:

Do not mail a second tax return.

IRS hasn't gotten my taxes.  It is lost in USPS mail.  I mailed it Priority mail 2 weeks ago.  It is listed as still in transit with no new update since over a week ago.
