The IRS states that the amount you are repaying for the First Time Homebuyer Credit is more than what you owe back.
To edit this form, please go into the Federal Section -- Other Taxes -- Form 5405 First Time Homebuyer Repayment.
If you need to look up the amount of your First Time Homebuyer Credit, please visit the IRS website's First-Time Homebuyer Credit Account Look-up tool.
If you have confirmed the amount with the IRS tool, you must print, sign and mail the return as the rejection comes from the IRS.
