Can an unprocessed refund be carried over to next year's filing?

I know there are still 39 days left in the year, but I am not optimistic that I will be receiving my refund in 2020, as I filed back in mid-March. Is there a way to have an unprocessed 2019 refund credited toward my 2020 tax filing? I am hoping that perhaps I will get my refund faster this way. It's a large amount, and money I desperately need.
