IRS says AGI doesn't match their records, the 2017 return with the AGI on line 37 of the Federal 1040 is still correct. Why the rejection?

[Ms-GAM]

The return was mailed not E-Filed for 2017. Not sure if that's the reason. Have refiled the return, still being rejected.

[Lisa995]

Was it mailed in late in the year?   If so, try using 0 as the AGI.   Returns filed late in the year may not have their AGI updated in the IRS Efile system properly.

[Opus 17]

Try zero, if not, print and mail your return.  Don't forget to also print and mail your state return if needed; in most cases, your state return is not transmitted if your federal return is rejected.  Make sure to check the status of your state return.

Some e-file rejections just can't be fixed even if your info is correct.
