If my dependent's name does not appear in the "Choose a name..." dropdown menu for the Child and Dep. Care, but is already under my dependents, what should I do?

You can enter her name there.  But, why wouldn't it just populate.  Check her age of the child.

 

To qualify for this credit, you must meet all of these criteria:

• You (and your spouse, if filing jointly) must have earned income.
  • The earned income requirement for one spouse is waived if s/he was a full-time student or disabled (if they lived with your spouse for more than 6 months in 2020).
  •  
• You paid caregiving expenses so that you (and your spouse, if filing jointly) could work or look for work.
  • The work/look for work requirement for one spouse is waived if s/he was a full-time student or disabled (if they lived with the other spouse for more than 6 months in 2020).
• You paid a caregiver to care for a Qualifying Person. The caregiver can't be:
  • Your spouse
  • Your dependent
  • Your child if they were under 19 on the last day of 2020, even if not your dependent
  • The parent of the Qualifying Person, if the Qualifying Person is your child under the age of 13 during 2020
• You can't file with the Married Filing Separately filing status (except under certain circumstances).
• You must furnish the care provider's name, address, and (unless it's a tax-exempt organization) their SSN, ITIN, or EIN on your return.

The credit is worth anywhere from 20% to 35% of your qualified expenses, up to $3,000 (for one qualifying person) and $6,000 (for two or more qualifying persons). Your percentage depends on your AGI, with the higher percentages applying to lower incomes and vice-versa.

 

TurboTax will determine your eligibility and calculate the maximum credit allowed.

Thank you for your response.  I tried entering her name there and that doesn't seem to be an option.  She is only 9 months old.   

Did you enter that she lived with you all year or just 6 months?

 

There is a message in the instructions that if she was born during the year to enter that she lived with you "the whole year" instead of just selecting 6 months.

 

If you only entered six months then go back to the dependent section and change it and that should fix your problem.
