Third Stimulus Amount

Turbotax says my husband and I qualify for a $2800 third stimulus payment. Last year we received it in the amount of $4200. It asks if we got $2800 and if not, enter the amount we received. My question is a multipart question. 

 

First, I thought the third stimulus was $1400 per person. I assumed that $4200 we received was $1400x3 for each of my husband, daughter, and myself. Is that wrong? Both my husband and myself each got form 6475 from the IRS. Both of them stated we got $2100. So does that mean my daughter didn't receive the third stimulus and qualifies for it? She made under $10000 last year. Would that go to her this year, or to us since she was our dependent last year?

 

Where it asks did we get $2800 and if not enter the amount we got. Do I enter $2100 (as in $2100 each?) Or do I enter $4200 (as in $2100 combined?) I would think if I am to combine the amounts, it would say we were eligible for $4600 ($2800x2).
