Retirement tax questions

here is how I do it: 

 

in forms view (I use the desktop version), there is a form called "qual div / cap gain".... look for line 7 - THAT is the income subject to ordinary taxes (if you follow closely, the form is subtracting out capital gains and qualified dividends, etc. to get to line 7)..... so if that line goes above $78,950, you've exceeded the 12% ordinarily tax bracket and have entered into 22% tax bracket (I assumed married joint).

 

is that what you are trying to figure out?
