Yes, exactly. So, the epilogue scene should've happened sometime soon before or soon after Regina went to the New Enchanted Forest to help adult Henry.

The epilogue scene of Once Upon a Time HAS to take place AFTER they get back to the future. Many years after the epilouge scene of Once Upon a Time in Wonderland.
