TurboTax does not receive any information from the IRS or state after you file your tax return.  So TT does not know if or why the IRS or state changed something on your return or reduced your refund for some reason.  You will receive a letter of explanation from the state or the IRS.  It is not clear from the way you worded your question which refund you are referring to.  You mentioned amounts of $690 and $1252--but we cannot see your tax returns.  We do not know if you are referring to federal or state amounts.

You can call the IRS hotline at 1-800-919-9835 to get updates on your stimulus payment.

The stimulus check is an advance on a credit you can receive on your 2020 tax return.  If something went wrong or you did not get the stimulus check this year, you can get it when you file your 2020 return in early 2021—if you are eligible.It will end up on line 30 of your 2020 Form 1040.
