Are you sure you have not misplaced a decimal point somewhere? If you had 10 million dollars of income what are you doing using do-it-yourself tax software?
just split up the W-2 you received into two pieces as a work around... and the FICA is capped at about $120,000 times 6.2%; but yes, the medicare 1.45% never stops and of course there is the .9% ACA tax as well.
but as noted above, the workaround may be paying an accountant!........ and a tax accountant and an investment advisor and a financial planner and an insurance agent and an adoption lawyer (so we can figure out how to adopt me!) 😀
