Q. Am I correct about being owed the money and if so how do I include that info here?
A. Not exactly. As explained at your other post ( https://ttlc.intuit.com/community/taxes/discussion/i-have-joint-custody-and-claimed-1-3-last-year-am...), you must claim the children as dependents (and your ex must NOT claim them) on your 2020 tax return, to get the Recovery Rebate Credit.
