Huge Increase to Refund Amount?

Hello everyone,

 

I still haven't filed my return as I'm waiting for a tax form. However, when I first entered all my tax information I had a very different return amount than when I just checked. By a "very different" amount I mean by over $1,000 more than the last time I entered tax information. 

 

I'm lost and a little worried to officially file anything as this is just a drastic change in what I was originally supposed to get in my return. I've gone through and reviewed all the tax information and documents I have entered and everything appears to be valid and correct. Nothing should have changed in terms of what I've entered. 

 

The last time I checked on my return it was before the most recent stimulus that I did receive. Maybe that could have something to do with it? Any information or advice would be greatly appreciated.
