Go back to the beginning of My Info and click edit by your child's name. You must have missed a screen or a question.
Children born in 2020 were not included in the 1st stimulus because those checks were based on 2018 or 2019. But on your 2020 tax return you can claim your child born in 2020 for the stimulus money, as well as the other child-related credits. You enter your new dependent in My Info. When you go through the screens in My Info make sure to say your child lived with you the WHOLE year. When it asks the oddly worded question about whether your child paid for over half their own support say NO.
The stimulus check is an advance on a credit you can receive on your 2020 tax return. If something went wrong or you did not get the stimulus check this year, you can get it when you file your 2020 return in early 2021—if you are eligible.It will end up on line 30 of your 2020 Form 1040.
We know that the IRS is already revising the 2020 Form 1040 to include the 2nd stimulus, but that change will entail a lot of re-programing at the IRS and for the tax software programs. It may be at least a month — or longer— before the forms are changed. Do NOT be in a hurry to file your 2020 tax return until more is known. Give some extra time to the IRS and the software programmers so that the software can handle the new 2nd stimulus, so that you can get it all by filing ONE time. You will need to visit the recovery rebate section AFTER the form and software revisions are complete in order to do this correctly. It is never a good idea to file too early; filing your 2020 return too soon may result in a lot of extra confusion that can be avoided if you wait and file a little later.
You may have to just delete him as a dependent than then re-enter.
For a child born in 2020 you need to make sure that you have selected he is your child, your son and None of the above for being adopted or a foster child, his date of birth is correct, that he lived in you home for the whole year, that he did NOT provide over one-half of his own support and that there was NOT another person in the home providing him support.
