Is it to late to file for my stimulas check only?

You can still file a 2020 tax return to get the first and/or second stimulus EIP amounts if you did not get them and if you are eligible for them based on 2020.  You have to file a 2020 tax return and use the recovery rebate credit section of the software to get that money.   There is no place to enter anything about the 3rd stimulus but the IRS is still sending out those payments so if you get your 2020 return filed you may still get the 3rd stimulus later too.

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 in 2020, you can get it when you file your 2020 return in early 2021

The Recovery Rebate Credit will be found in the FEDERAL REVIEW section. ( you should see "Let's make sure you got the right stimulus amount”)  If you are eligible it will end up on line 30 of your 2020 Form 1040.

Make sure that you enter ALL of the stimulus money received for the 1st and 2nd stimulus for yourself, your spouse and your children.

TurboTax cannot track your 3rd stimulus or tell you when it will arrive.  The IRS is issuing 3rd stimulus checks on its own timetable.

You can use the IRS Get My Payment site to see what is expected for your 3rd stimulus check:
