Deductions & credits

Hi,

 I got the first round of stimulus payments totaling $2900 (married filing jointly ) plus $500 for my son, that was all correct.

But In the second round, I only got $1,200 (for me and my husband)

It was supposed to be $1,800 because (married filing jointly) plus $600 for my 8 year old son.

The turbo tax software showed the amounts that I received as $2900 from the first round and $1200 from the second round. It would not let me apply the missing $600 that was missing for my son as the recovery rebate.

When I entered the amount I received as $1200, it said you received the correct amount so you do not qualify for the rebate.  I've tried calling the IRS and they just transfer me to a line that says to try back later.
