Amended tax return rejected

Hi,

I have e-filed my federal return, which has already been accepted (but not yet received refund). Later I found that I missed a 1099-INT form to report. Therefore, I made the edit in TurboTax Deluxe Windows desktop version and get it passed all necessary check. 

However, upon e-file my amended tax return, it was rejected and the email from TurboTax says -

F1040X-041 - If Form 8888 is present in the return, then Form 1040-X, 'RefundAmt' must be equal to Form 8888, 'TotalAllocationOfRefundAmt'.

 

I checked and could see that on my form 8888, TotalAllocationOfRefundAmt is my updated refund amount, which is less than the original tax return. On form 1040-X, RefundAmt is empty because I'm owing money on line 20.

 

So how should I file the amended tax return in this case? Thanks in advance!
