If you left with a re-entry permit your extension and permission to stay is still valid and you can’t apply for a new visa. You therefore need to enter on your current extension and do a border bounce to get a new 60 days visa exemption when it expires. If you hold a Italian passport you don’t need a 60 days tourist visa as you’re entitled to a 60 days visa exemption. I would have used a professional landborder company for the border bounce. If you didn’t get a re-entry permit before you left, you can apply for a 60 days tourist visa if feels more convenient for you since you’ve already had a long term stay.
