How to sync my filed version with desktop

I desktop filed my Federal and got a notice that the IRS accepted the return. 

Then my HDD crashed. I was able to restore an older (pre-filing, slightly different) .TAX file. (I added some lines and I think I have restored what was filed.)

Of course, the desktop .TAX file says it has not been e-filed yet. I would like to get the IRS acceptance and sync up my desktop .TAX file with the official version.

How do I sync up my latest filed version with my older desktop version?
