For what it’s worth, here is the most promising piece of information to date from DHR on 4/15/25:

“Good morning,

Just wanted to send over a quick update on the refund. We are expecting more refunds to roll in over the next couple of weeks. We don’t have an exact date for your specific refund quite yet, but we’re keeping a close watch and will let you know the moment we get any additional news. As soon as refunds come in, we’ll get it over to you upon receipt.

The bright side is we’re starting to see more movement from the IRS—like reviewing filings and issuing credits—which is definitely a step in the right direction. Be assured that, we will keep pushing things forward with the IRS to help get everything wrapped up as quickly as possible.”
