Retirement tax questions

On the face of things, None of those (lines 7, 17 or 22) would cause line 71 to be so high.

Perhaps an usually high $$ amount on lines 57 or 58 might do it, but it would seem that line 12 or 17 of the form 1040 would have to be much higher.

or......A mis-entry of some of the other data from whatever form you used to enter the line 17 $$  (I'm not knowledgeable to know what form is used for your 5% ownership....and if it has SS withholding on it)
