2021 recovery rebate credit amount

I am trying to figure out if I got the correct amount for the 2021 recovery rebate credit.  My 2021 AGI was $146,000.  It is myself, my husband, and 3 kids, who are all dependents and not claimed by anyone else.  We received $3500 as the third stimulus rebate. I was under the impression it was $1400 per person, including dependents.  Would that mean it should have been $7000? Do I need to do anything? I filed using turbotax.
