iCloud Inactive in Internet Accounts

Internet Accounts on MacBook Pro shows iCloud Inactive with the message "This is not your primary iCloud account" and there are question marks where my name should be.

Also, all of my files in iCloud Drive disappeared and I had to restore them, but not all of them downloaded.

In addition, I am able to send mail from my iCloud account, but am not receiving them.

I do not have these problems on my iMac so I am hesitant to delete anything as per some of the solutions I have seen for related issues.
