Contributions to a Roth IRA aren't deductible (and you don't report the contributionson your tax return), but qualified distributions or distributions that are a return ofcontributions aren't subject to tax. In addition, you don't have to be under age 70½ to contribute to a Roth IRA. https://www.irs.gov/taxtopics/tc451
so therefore no you do not need to amend.
TT holds this information history for you though so you can track your basis in the IRA.
I hope this was helpful?
