So, Turbotax apparently had a glitch and I didnt claim EIC. IRS sent me a notice. How do I add that to my amended return?

I talked to IRS after sending in my form but they never received it and said my best bet is file an amended return. I cant find the option to add form 1040x.

If you were eligible for EIC the TurboTax program would have entered the EIC on your 2021 Form 1040 Line 27a.  You were asked if the 2019 Adjusted Gross Income was greater than your 2021 AGI and if so you should have use the 2019 AGI to calculate the EIC.

Use the IRS assistant to verify that you are eligible for EIC - https://www.irs.gov/credits-deductions/individuals/earned-income-tax-credit-eitc
