We are a family of 5

Turbo tax says based on our income, we should have gotten $3710 for the3rd stimulus payment, in actuality we should have gotten 7000 (5 total) but only received 5600. Will the IRS see that I am still owed the 1400 even  though the software is not picking it up? They are basing it on 2021income instead of 2020. We received the 1st 2 stimulus payments for the 5th person in the recovery credit of 2020 taxes....
