Penalties when filing on time, but return is not accepting and have to mail?

Hi,

For still unexplained reasons the IRS did not accept my electronic filing the last 3 years.  I'm trying again.  Same bank, same location (lived here 28 years).

But, now I see that after filing it tells me that I may not find out if it's accepted until Sunday Oct 17.  If it gets rejected and I have to print/snail mail it, then it will be late and I'll have to pay penalties again.

 

So, how do I get credit for filing by the correct time when I get rejected after the expiration date?

 

Thank you for your  guidance,

Stephen
