The quest line for the Redemption Skill begins with a 2 part quest that rewards an item
Tome of Divinity. The quest chain is continued by right clicking on that item.
If the item is deleted by the player or at some point the quest was bugged and the item was not rewarded, it is impossible to complete the quest.
Please check if this quest item is in your bank or inventory somewhere, if it is you will be able to continue the quest line.
If you do not have the item in your inventory, the dev's are working on a solution to allow you to get the quest item again if you have already completed the quest. Once the fix is in place, you will be able to speak with the NPC that awarded the Tome of Divinity previously to receive a new one.
