Refund less than expected

Turbo TAX sent in federal tax with refund of $5,234.00

Why did IRS change tax refund to $3,834.00 (minus $1,400) ?

Checked ITS2GO  see below

What is this  deduction? Actual Deposit in my bank from SBTPG $3,677.55 (minus $156.45) 

 

Total difference -$1,556.45

We changed the amount claimed as Recovery Rebate Credit on your tax return. The error was in one or more of the following:

  • The Social Security number of one or more individuals claimed as a qualifying dependent was missing or incomplete.
  • The last name of one or more individuals claimed as a qualifying dependent does not match our records.
  • One or more individuals claimed as a qualifying dependent exceeds the age limit.
  • Your adjusted gross income exceeds $75,000 ($150,000 if married filing jointly, $112,500 if head of household).
  • The amount was computed incorrectly.
