I'm trying to apportion sales in TX and I'm getting odd results on the forms generated.

Total sales = $3,657,962

TX sales = $443,179 - Entered this in gross receipts TX in the apportionment screen

When I enter $443,179, the form shows gross receipts in TX as $4,101,141 on line 24. Since that number exceeds total sales, the apportionment factor is 1.0.

I have no idea why. Can anyone explain why this is happening?
