Did not opt for deluxe

Your question is being posted from online Deluxe, so apparently you upgraded to Deluxe when you entered something that was not supported by the Free Edition.   If you used Deluxe and filed your return, customer support is highly unlikely to give you a refund.  You can try talking to them but do not expect a refund.

No one in the user forum can resolve a billing issue.  If you have a question about your TurboTax fees or billing, make sure you use the word “billing” in your request for help.  Do not use the word “refund.”

As for the $1400 difference in your refund---

LOTS of people have made mistakes this year with the recovery rebate credit by "forgetting" that they received the $1400 per person stimulus checks last year.  They answered no to the questions for the  recovery recovery rebate credit and put the $1400 per person on line 30 of their returns.  But you cannot get it twice, so the IRS removes it when it is there by mistake.

Try checking your online account with the IRS

Does the IRS show that you received a $1400 stimulus or EIP check in 2021?   Did you receive it?   When you were asked on your tax return did you say no?   Was there $1400 on line 30 of your tax return?

If the IRS says you got $1400 last year but you did not receive it you can have it traced.

If you need to trace a payment that the IRS says has been issued to you, mail or fax a completed IRS Form 3911, Taxpayer Statement Regarding Refund.
