Is there a problem with how TurboTax decides Other Dependent Credit vs. Child Tax Credit? The explanation disagrees with how the form is filled out this year

No. The parent who claims the child is the only one allowed to receive the Child Tax Credit (CTC) or the Other Dependent Credit (ODC). The custodial parent must sign Form 8332 to waive the dependent to the noncustodial parent. The ODC is available for children who are over 16 at the end of the tax year, 17 years of age or older.

What you need to know about CTC, ACTC and ODC

What is the $500 for Other Dependents?

• A qualifying dependent for ODC must:
  • Be a dependent claimed on your return.
  • Be a dependent who can't be claimed for the CTC/ACTC.
  • Be a U.S. citizen, U.S. national, or U.S. resident alien.
  • Have an SSN, ITIN, or ATIN that was issued before the due date of the return (including extensions).
• Limits on ODC:
  • For tax year 2018 through tax year 2025, you may be able to claim ODC.
  • The maximum credit amount is $500 for each qualifying person.
  • The credit begins to decrease in value if your adjusted gross income exceeds $200,000 ($400,000 for married filing jointly).
