After you file

I sent a copy of the letter from the IRS to the IRS Recovery Rebate Credit with a copy my 1040-SR tax return 2021, prepared by Intuit TurboTax. March 9, 2022, after Intuit Turbo Tax recommended I respond to the IRS notification via email after several attempts to contact Intuit Turbo Tax requesting assistance.  According  to intuit turbo tax my refund is $885.00. The IRS statement says I owe $515.00. I’ve used your establishment for years now. I don’t understand how there would be a miscalculation between the IRS or Intuit Turbo Tax. Can you assist?  I am waiting for my Federal income tax refund since February 20, 2022. Can you PLEASE assist?
