Sorry, I don't know if this will work, but you may like to try this yourself??  If so, this is what I have done in the past.

In order to save time, I think I, and not have to call tech support, I believe I did what you are suggesting.  I just entered the very few that I was trying to fix or make disappear to get rid of the red error I was receiving.  I then subtracted those 2 or 3 from the summary totals.  I then used all those numbers, and I was able to get the red error message, and finally make it go away.. All I had to do was make a copy of the rest of the PDF and attach it.  Mine did go through fine with the IRS at that point. And then I was able to move on to the next return.  

Good luck either way!!!!
