Retirement tax questions

thank you volvogirl for tax calc , line 16 info.  The secret tax calculation not mentioned in the 1040 instructions .

 

Question about Social Security mis calculation is still open.  The info from IRS didn't mention any other info being changed. And, like I said, my use of the taxable SS worksheet gave a different , higher amount than TT.  Using the same filed income, 1099-r amounts.
