What's the Wedding Gift Etiquette

My fiance and I were scheduled to have our wedding on 8/8/2020. But due to the continuing COVID-19 issue, we have postponed the big celebration out a year. We are still getting married this year with just our parents and siblings, but we will be renewing our vows and having the big celebration on our first year anniversary. We had already sent out our invitations before making that decision, which, of course, had our registry information. Prior to postponing, we had received a couple wedding gifts that were shipped directly to us. At the time, we were going to put them off to the side and wait to open them until after our wedding. However, putting boxes off to the side for a month or two is a whole different story than putting them off to the side for a whole year. We're also continuing receiving gifts that had to have been ordered after we postponed. So what is the etiquette here? I'm not sure if there is an etiquette rule written for this type of situation....... Do we set them aside for a year? Or can we open them now and send out the thank you cards now?
