I have a clarification here. I did a backdoor roth contribution. I reported the non deductible contribution in 8606 part 1 but forgot to fill out part II line 16 and 17.
What impact would this have and do I need to resubmit a correction?
Yes, you need to amend to include that information. For example, if you made a $7000 backdoor contribution and the bank assigned you $1 of interest, you either converted $7001 (so $1 is taxable income) or you converted $7000 (in which case you have $1 of basis left over). Even if there was no interest at all, you need to put it in writing so the IRS can't come back to you later.
