IRS letter 6475 confusion

Turbotax asks if $2800 matches the amount in Letter 6475.  It does match, so I answer YES.  Instantly Turbotax erases $2800 from our refund.  Huh?  Go back to try again and again.  A-ha.  I have to LIE and say NO, $2800 does NOT match the amount in Letter 6475.  Even though it DOES match.  Only if I say NO am I allowed to tell Turbotax we received 0 payment.

Helloo, Turbotax.  Just because Letter 6475 tells us we were issued a $2800 payment does not mean that we actually did get a payment!
