Can I still claim the Child Tax Credit if I didn't have any self-employment income in 2023?

It is my understanding that I can still claim the Child Tax Credit with no income. I think it's $2000, with up to $1600 refundable. Is that correct? I have joint custody of my child that lives with me more than 50% of the time and I alternate years with the other parent claiming them on my taxes. 2023 would be my year.

 

When I was working, I was self-employed. So, when my contract ended I did not collect any unemployment. I used TurboTax self-employed edition. Now that I didn't earn any income, do I still have to use the self-employed edition or can I just use the standard edition? I don't have a business license, I just file using my name.
