TurboTax logged me into the wrong Intuit account

This is a long story, but in summary Intuit never asked me for a password and logged me into the wrong Intuit account (not the account I entered and not the account to which they sent the 2FA code). Is Intuit's login process really safe and trustworthy if it's capable of this kind of screw up?

A less important question: TurboTax Premier 2025 for my personal taxes is now associated with my business Intuit account. Inconvenient but not catastrophic. Is there was way to move the license from the account that Intuit logged me into to the account that I asked Intuit to log me into?

Background: I have two Intuit accounts, a personal account and an account for my business. The accounts are associated with different email addresses and have unique passwords and credit cards associated with them. Both use the same mailing address (my one person business operates out of our house) and phone number. I'm using Windows 11 for both, and on the computer I have an administrator account that is separate from both the personal and business (non-administrator) accounts.

Yesterday I installed TurboTax Premium 2025 on my computer to get ready for my 2025 personal taxes. My business taxes have already been prepared using TurboTax Business 2025. I downloaded the executable from InstallTurboTax.com and launched it. It asked for administrator rights and I entered the administrator password. After several minutes TurboTax was installed and it asked if I wanted to launch the program. I clicked yes (in hindsight, a mistake).

TurboTax immediately asked me to log into my Intuit account by asking me for the account name. I entered my personal email address. Instead of asking me for the password Intuit sent a 2FA code to my personal email address which I entered (is it really a 2FA code when there is no first factor?). Intuit then sent a second 2FA code to my phone which I also entered. And then I was logged into my business account - not the account that I had entered into TurboTax. I saved the 2FA email and have checked it several times: it was sent to my personal email address. Once I was logged in I entered the license code, Intuit accepted it, and the program was running. I then tried to import my 2024 taxes and discovered that TurboTax was running under the administrator account and was therefor unable to access the documents in my personal account.

I then shut down TurboTax and launched it again but without administrator rights. Again TurboTax asked for my Intuit account, and again I entered my personal email address. Instead of asking for a password Intuit sent a 2FA code to my personal email address which I entered. This was followed by a 2FA code to my phone which I also entered. And then I was logged into my personal Intuit account (the one I intended) and asked for the license code. When I entered it, it was refused because it's already in use. After an hour talking with support (lots of ideas, but no joy) and another hour exploring alternatives (uninstall, reinstall, and more) I looked carefully and discovered that while my personal Windows account was logged into my personal Intuit account, the Windows administrator account was logged into my business Intuit account. Logging out of my personal Intuit account and then logging into the business account now allows me to run TurboTax from my user (non-administrator) Windows account.

At this point I dug out all of the emails that Intuit sent to me and carefully checked the addresses (multiple times!). Everyone of the 2FA emails from Intuit was sent to my personal email address, nothing at all was sent to my business email address, yet somehow the first time I was logged into my business account and the second time I was logged into my personal account. I was never asked for a password for either account. Is Intuit's login process really safe and trustworthy if it's capable of this kind of screw up?

Is there some way to fix the result of Intuit's login error or will I have to live with using my business Intuit account for the rest of my use of TurboTax 2025?
