Married and filled jointly. No kids. First stimulus check was $2k short. Income was below the $150k threshold. No recovery rebate credit option after "review". Why?

You should have received $2,400 for the first stimulus payment as shown here from the IRS EIP1 page.

We issued payments of $1,200 ($2,400 for a joint return) to individuals whose adjusted gross income (AGI) did not exceed:

• $150,000  if married and filing a joint return
• $112,500 if filing as  head of household or
• $75,000  for eligible individuals using any other filing status
  Payments were  reduced by 5% of  the amount by which your AGI exceeds the applicable threshold above.

You should have received $1,200 for the second stimulus payment for married filing jointly as shown on the IRS EIP2 page

.

The third stimulus is not paid in full when the first payment is made and is not included on the tax return.
