I got an IRS notice CP08 to fill out 8812 but turbo tax does not give me the option to fill out that form online. I wanted to do it here since they already got my info.

The IRS notice CP08 and Form 8812 are related to the Child Tax Credit. TurboTax will automatically fill in Form 8812 based on your answers in the system if it is required for your return. To enter the information regarding this IRS notice and Form 8812:

1. You should also have received Letter 6419 from the IRS which states the amount of Advanced Child Tax Credit if you received any. If you received advanced payments, but do not have that letter, you can get the information from the IRS website. 
2. In your TurboTax return search for Child Tax Credit and use the Jump to link then Continue.
3. Answer the question on the Let's start with where you spent the most time in 2021 screen and Continue.
4. On the Tell us about any advance Child Tax Credit payments screen, answer Yes, enter the amount from your letter in the Tell us about any advance Child Tax Credit payments box, and Continue. If you did not get advanced payments, enter 0.
   1. If your spouse also received payments, be sure to enter that amount as well as a combined total for both of you.
5. Answer the questions on the following screens, confirm your amount on the Let's recheck your advance Child Tax Credit payments screen, and Continue.

Please follow the steps from @RaifH above.your post. The most important thing is to be sure the total amount entered is the total received for both of you.

For example: Your family received $1,800 in advance credit. You may have one of you with $1,800 and the other with $0 or if both are parents, you would have gotten $900 each. The total for the two of you needs to equal the total received.

See pictures here from @Critter-3 but your answers are different since you will say yes to receiving the credit.
