I’m having a little trouble understanding that.

As iCloud Keychain and two-factor are both enabled, this should share passwords.

That’s all from this, as was linked: Make your passwords available on all your devices with iPhone and iCloud Keychain - Apple Support

Two factor authentication cannot be disabled, after having been enabled for 14 days.

To the OP: As you’ve mentioned that Apple Support is not available in your country, are you possibly located in an “embargoed” country? if so, then various Apple services including iCloud Keychain may or may not be available, and may or may not work.

Shut off iCloud Keychain on both the Mac and the device, restart the Mac and restart the device, and then re-enable iCloud Keychain. Select "keep" and "merge" through this whole sequence too, when trying to get iCloud to resume playing nice.

No , don't disable 2FA before 14 days if 14 days are crossed the account is permanent , from iPhone sign in with same Apple ID and password on the same network , the code will go to iPhone you have to approve from iPhone to sync ( avoid using iPhone passcode ) .

When 2FA account is set permanently the keychain box looses its value , its checked or unchecked doesn't make sense , iCloud Keychain is utilised upto secondary authentication account in which three answers for security questions , date of birth , rescue mail address and its password are added .

In the starting I mentioned the two articles for iCloud Keychain , they clarified later about 2FA .

Secondary authentication - setting up iCloud Keychain between devices , direct sharing of passwords will occur .

In 2FA account , a second step has to be enabled approve the Mac and iPhone .

See the articles Set up iCloud Keychain - Apple Support

If iCloud Keychain won't turn on or sync - Apple Support

Same Apple ID on all, presumably.

I suspect you’ll need to contact Apple Support, then.

Post a screen shot of system preferences , click on Apple ID , hide your mail address / pic .

Is the account set up with 2FA or secondary authentication .
