After federal filed and return accepted on Mar 13, recent TurboTax 2020 update says i have more for refunds federal and state, what ?!

I Hello,

I've been using TurboTax, oh, for >25 years.  This year 2020 seem to be, for what i can remember seem to be more finicky than any previous, eg. ESPP adjusted cost basis as an example.

Anyway, last week Mar 13, completed both federal and states, filed e-return for federal. Got notification saying federal has been accepted and i've been just waiting for refunds to be issued.

On Mar 13, the refunds shown by TurboTax 2020 were,

$5,786 (federal)/$572 (state)

With recent TurboTax 2020 updates in past few days, the refunds for the SAME returns are now saying,

$6,675 (federal)/$718 (state)

What ?!

I usually wait until close to Apr 15'th to file my returns, this year 2020 filing decided to go little sooner to see if i can get in for the 2020 covid stimulus check #3.

Anyway, what does this mean?  Do i need to file amends?

This is very confusing, as in my ~25 years using TurboTax, never have i come across this scenario.

Anyone run into this sort of situation?

Thanks.
