Retirement tax questions

@DoninGA -- It's very kind of you to respond.  Perhaps I am only allowed to use tax tools after I pay?  As I am trying to finish this my choices on the left are limited to "Tax Home" and "Documents" then a very large space where I imagine something would someday emerge.  At the bottom are File an Extension and 3 others, but no Tax Tools.  Gosh, this is frustrating.  As a self-emplyed person, every other tax product asks if I have or want a SEP.  Answers?  I have one and I want to contribute a little more!
