@luciow67 I can tell you below how to find multiple accounts and gain access. But there is no way to merge them. You'll need to choose one and remember it going forward.
[ADDENDUM NOTE 2/14/2025 at 11:45 PM Pacific:
If you used Online TurboTax for 2023 and plan to for 2024, you should use the same one that you used in 2023 if you are going to prepare the 2024 return in the same online account, since the 2023 information should flow into your 2024 return if it's the same account.]
FAQ: Can I merge my Intuit accounts?
https://ttlc.intuit.com/turbotax-support/en-us/help-article/account-management/merge-intuit-accounts...
How to look for and regain access to multiple accounts:
You can have up to 5 accounts that use the same email address for notification purposes. A User ID may be an email address, but it doesn't have to be. It might be only part of an email address, or it can be anything at all.
To get a list of your User IDs, reset password, and recover account access, etc., you can use the tool at the link below. When using the Account Recovery tool, try using your phone number first if you can still access it. If that was unsuccessful, then run the tool on your email address(es) you can access.
NOTE: Before running the account recovery tool below, log out of all Intuit accounts including this user forum, or you might end up in a loop. Then clear your browser Internet cache, close your browser, then reopen it, and go to the link below. You may wish to copy this link so you can paste it into the new browser session.

If still no luck after running that on your phone number you can still access and email address(es) that you can access, here's another method:
Go back to the tool again, but this time leave the data field blank, scroll down a bit, then choose the small blue link that says "Try something else", and it will look you up by other parameters.
