Entered wrong routing number but used 'Pay With Refund.' Bank says 'Account Not Found' as money is in transit. How to stop a check to a vacant address and force RTT?

I filed my 2025/2026 return using the 'Pay With My Refund' option, meaning my funds are being processed by SBTPG/Green Dot Bank (or Cross River Bank) to deduct my filing fees. I inadvertently provided a Capital One routing number with a Venmo account number, which will result in an automatic rejection once the deposit is attempted. I am currently located in Fiji and no longer have access to the Hawaii mailing address on my return, making a physical cashier's check a high-risk scenario. Since the bank's automated system currently shows 'Account Not Found' while the money is in transit from the IRS, I need to know the exact window for requesting a Return to Treasury (RTT) before their system defaults to printing and mailing a check to my vacant US address.
