Windows 10: Changing my Individual Microsoft account to an existing Microsoft 365 Family Plan.

I have a Microsoft account but my wife has a Microsoft 365 family account. I would like to be on her Family account and stop my Individual Account. We are unnecessarily paying for 2 separate Microsoft accounts Can I join her plan without losing my Data? Most worried about One Drive If I can change to her plan and not lose my data, how should I proceed?THX

Microsoft account does not exist error - but it does exist...

Another example of my confusion:

Step 1: Windows/Start button is pressed in the bottom left.

Step 2: Above "Power", "Settings", "Pictures" and "Documents" is my account/email address that I'm currently using to post this question with (which also is the Microsoft account I have my 365 subscription tied to). I click on my account with my personalized icon.

Step 3: Above "Sign out" and "Lock" is "Change account settings" which I click.

Step 4: I'm brought to "Your info" which has my personalized icon, correct email address, listed as the administrator too. I select "Manage my Microsoft account" and am taken to account.microsoft.com and logged in to the same correct email/account. I can see on this page my 365 family subscription is still active and fine.

Step 5: I go back to the "Your info" pop up settings window and below "Manage my Microsoft account" is another link to "Verify", of which I click.

Step 6: The small Microsoft Sign in window appears with prepopulated text saying that the same exact email address that I'm signed in on my computer using, (of which has active 365 subscription and has no issues seen on account.microosft.com when I log in) doesn't exist. The exact text is as follows and red: "That Microsoft account doesn't exist. Enter a different account or get a new one."

Step 7: When trying to re-enter the same email address, and clicking "Next" in the bottom right of the window, the red text persists that the account doesn't exist.

I can't comprehend how my correct email address which has Microsoft subscriptions simply can't be found or 'doesn't exist'.

Apologies for the long-winded questions, but I'm trying to be as thorough as possible so that anyone can review this and hopefully have a better understanding of the issues I'm having. I'm getting a bit desperate to have this sorted out and any solutions would be extremely valuable to me.
