My ex-husband and I split the stimulus payments. When it asks how much I received, do I put the full amount we received, or just half the amount that I got?

Filed 2019 taxes together.  Received first stimulus payment 4/2020. Divorce finalized 12/2020.  Received second stimulus payment 1/2021.  We split both of the payments received.  We are filing 2020 taxes separately.
