I forgot to do my backdoor Roth conversion last year. I had an existing Vanguard Traditional IRA with $1.85 in it. Last week I contributed $12K (after tax money) from my brokerage account into it, specifying to put $6K in 2020 and $6K in 2021. A few questions:
1) When I try to convert to Roth IRA, it doesn't let me specify years. Because I did that when I first contributed, can I convert the whole thing without worrying about exceeding any yearly limits?
2) If yes above, will the $1.85 matter, or should I specifically convert exactly $12K?
3) Any tax forms to file? I believe I've been told I need an 8606. Any others?
4) Would I report is as part of my 2020 taxes, or 2021?
5) Any deadlines I need to know about other than 4/15?
Any guidance would be greatly appreciated!
