2021 1120 efile rejected
Hi,
I have tried efiling my 2021 1120 form for C Corp, but turbotax business tells me it has been rejected and I need to call IRS efile help desk. I tried calling but was never answered. The reason I used efiling was that my mailed tax returns were delayed for the past two years and I kept receiving notices from IRS that I filed too late. Anyway I can get help here?
Thanks!
