Retirement tax questions

I just installed Windows Home & Business.  I didn't get the excess message so I put in 10,000 for SS.  Got the "Looks like you are due a refund from your employer"  screen.  It shows the right amount of $9,932.00 BUT the screen should show the actual amount with cents of  9,932.40.  I kept putting in too much SS amounts and didn't get the excess screen until I entered 9,937.10!  They might need to fix that.
