Why did my accepted to back to pending?

From what I am seeing, your status changes to pending just before a deposit is made.

While you do get a date from the Internal Revenue Service as to when your refund should be available, they do not specify exact times. If you have a deposit date of today and have not received your refund yet, be patient.

There are no fixed times or hours when you can receive your 2024 tax refund during the 2025 Tax Season.

Additionally, each bank varies on when they post direct deposits. Even if your bank "usually" posts direct deposits at a certain time, they may handle Tax Refunds differently. Some banks might post once in the morning and once in the afternoon, only one time a day, and some may instantly.

In the Community, we do not have access to your TurboTax account and can not tell you where your refund is or why you do not have your deposit yet.

If your refund date has passed and you have not received your refund, it may be that your direct deposit, for a variety of reasons, was not able to be completed and your refund is coming as a paper check to the address on your return.
