Retirement tax questions

This is exactly my situation.  I have allowable catch-up contributions. 

 

Your reply "The only way to fix this when filing an original tax return is to be using the desktop version of Turbotax installed on your own computer and overriding the calculation.  Overrides void the accuracy guarantee and can't be e-filed."

 

I have the desktop version.  When you say "override the calculation". Where?

 

Thank you!
