I'm in a registered domestic partnership in California and I'm following these steps: https://ttlc.intuit.com/community/family/help/how-do-i-prepare-our-rdp-return-if-we-live-in-california-nevada-or-washington-state/00/25662.
Question: On the "Tax Withholding Adjustments" screen in the TurboTax desktop software, there is a box for "Federal Amount". In addition to the federal income tax (Box 2 from W2), should I also add in this box ("Federal Amount") the allocated amounts withheld via Social Security and Medicare taxes?
I wasn't sure whether to purely fill in this "Federal Amount" box with only federal income tax. Or if I should also be including Social Security tax and Medicare tax.
