Thank you @fanfare . I just checked Turbotax eFiling status and they came back accepted. Now, how do I use it to file the 1040-x?
I found the following article on filing the amendment:
https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-federal-tax-return-curr...
On the 4th bullet point, the article says "Once you begin your amendment..." but it doesn't say how to do it!
btw what I forgot to do was add my Social Security benefits to my income. That's all that needs to be corrected.
