iPhone and my iPads are usually NOT filling in id’s and Passwords they have private browsing is not open but I do use it.

Greetings George Apple,

We understand that AutoFill  is not working as expected. To clarify did you complete the steps in the following resource that you were reviewing:

If iCloud Keychain won't turn on or sync

"If Safari doesn't autofill your account names, passwords, passkeys, or credit cards, or doesn't ask to save them, make sure that you have the latest version of iOS, iPad OS, or macOS on your devices.

If the issue remains, follow these steps to check the AutoFill and Private Browsing settings on your device.

On your iPhone or iPad

• For account names and passwords: Go to Settings > Passwords > Password Options. Then check that AutoFill Passwords is turned on.
• For credit card information: Go to Settings > Safari > Autofill. Check that Credit Cards is turned on.
• Turn off Private Browsing: Open Safari. If the navigation bar in Safari is black or dark instead of white or light gray, turn off Private Browsing. Safari doesn't save account names and passwords when Private Browsing is on. 

Still need help to autofill credit card information? In Safari, tap the credit card field, then tap AutoFill Credit Card above the keyboard."

If so, and the issue persists, we suggest that you reach out to Apple directly concerning this issue. You can follow this link to connect with them: Get Support

Best wishes!
