No one else can see your tax return so we do not know why you owe. There can be many reasons why you owe tax including not having enough tax withheld from your paychecks, collecting unemployment and not having tax withheld, losing the child tax credit if a child turned 17 during the tax year, entering some data incorrectly, etc. etc. etc. You should print out your return to compare it line by line with your 2019 return to see what the differences are.
As for your stimulus---did you use the recovery rebate credit on your 2020 return? You need to do that so that any stimulus still not received can be included as part of your 2020 refund.
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 ad 2nd stimulus for yourself, your spouse and your children.
