The IRS incorrectly entered into their system, the amount of my refund

The amount of your refund is shown on line 35a of your Form 1040.   Why are you saying the IRS entered an incorrect amount?   Did you receive a reduced refund?   If the IRS reduced your refund they will mail you a letter in a few weeks to explain the reason for the changed amount.

The refund from your federal tax return is on the Form 1040 Line 35a.  This is the amount you enter on the IRS website for the status of a tax refund - https://www.irs.gov/refunds

Or did you mean something else and if so, please explain.
