Are you asking about your 2023 refund for next year?
It's too early to get an Advance. We don't know if they will offer Advances next year. If they do, you can't apply for it. Only if they offer it to you when you file.
When you go though the FILE tab right before you file, but....
The Advance doesn't come until after the IRS ACCEPTS your return. Usually the IRS won't start accepting returns until late January. Until then the returns just wait on Turbo Tax servers for the IRS to open. So filing early won't make a difference.
