1. I am following the advice outlined here: https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-prepare-a-joint-federal-return-and-se... (which continues to be not at all user-friendly and just a recipe for a user mistake-- it's disappointing that TT can't do any better than this year after year)
DC asks you to enter "income received while residing outside of DC." What am I subtracting my DC income from? The AGI number on the true married filing jointly federal tax return? The taxable income line? The AGI number on my mock married filing separately federal tax return? The taxable income line? I assume the real number because DC obviously never sees this mock return, but, again, there's not enough clarity around this process.
2. I lived in DC for the first 9 days in 2019. My wife lived/worked in DC for 0 days. Obviously the DC W-2 goes to DC income. What about jointly held securities/dividends/interest etc? Do I have to figure out how much interest/dividends/other income we earned in the first 9 days of 2019 and split that 50-50?
