TurboTax is saying that I paid more in Federal Income Tax than what I'm showing was paid in on my W2 and 1099-R. Where do they get their calculation?

TurboTax is stating I paid in $84 in Federal Income Tax.  My W2 is showing $38.50 paid in Federal Tax and $1.93 in RI-SDI.  My 1099-R is showing $3.69 paid in Federal Income Tax.  I can't figure out where TurboTax gets the $84 paid in?
