I'm seeing this thread rather late, so maybe you've resolved your issue by now. Hope so, but in case not...
Just our experience: My Turkish husband, who had a 10-year green card, was out of the US longer than 1 year a couple of times, for family reasons...but not for any of the really, really good reasons you have (esp Covid). He had to schedule an interview at the US embassy in Ankara both times to get the OK to return, and they gave him some sort of official re-entry permit slip to hand to Customs along with his Turkish passport and US green card when he returned.
