Thank you for the detailed answer. That was very helpful.
I followed the path and checked my 1040. Looks like this little error with my youngest kid goes back to 2019 taxes. On this year's I could click the box on the 1040, though that didn't save. I ended up deleting him and then reentering him. That fixed it. I then went back though my deductions to ensure things calculate appropriately. All looks in order.
I had a look at the 2020 taxes. Unsure if I'll crack that nut, though I'll have a closer look to see if an amendment is worth it, before I file 2021.
I may have to submit another question - Let me know if I should... Regarding the third stimulus check and the recovery rebate, calculators on both TurboTax and another online both indicate that I (my wife and I combined) should have received $10,773, though we only received $8079.12. When I try to reconcile this on TurboTax in the federal review, it only boosts it an additional $321, for $8,400 total, which aligns with the AGI of $141,923 and 4 dependents. For 6 dependents, it says it should be $11,200.
