I only claimed my First Time Home Buyer's credit one year while I lived in my first home. Is there anyway I can go back to claim it?

The only federal first time homebuyer credit existed from 2008-2010 during the housing crash.  There have been no other credits since then.

The First Time Home Buyers Credit  no longer exists so you can no longer "claim" it.

Also, if you received the homebuyer credit in 2008, you may still have a reporting and repayment responsibility.  See the 2008 HomeBuyer Credit Repayment interview in Deductions and Credits > Your Home (screenshot below).

It's a one time credit.  You don't get to keep claiming it every for the same home.
