I just realized that I accidentally underreported my income on last year’s taxes. (It was my first year doing them myself.) What should I do?

You can amend the 2023 tax return that you filed to correctly report your income.

See this TurboTax support FAQ for amending a prior year tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...
