At any rate, I was able to still efile despite making the changes in a way different than what you recommended. I had my fingers crossed the entire time!
There's a real glitch in the summary tables comparing diff years - it says, for example I received a refund of approx 160$ but didn't account for the fact that I paid (as part of my extension request) $1700. So really TT should have indicated I PAID approx 1540$ and not a refund of any kind.
