State extension payments made in 2018 for 2017 were unnecessary. How can I net the full extension payment against the refunds reported on 1099-G?

I entered information about extension payments to both states and the refunds received.  TT is making a calculation that nets only a small portion of the unnecessary extension payment against the refund.  I itemize and with the limit on state and local tax deduction on Schedule A, this results in my reporting more income than appropriate.

I SHOULD be able to net the full extension payment against the refund.  How can I make this happen?

Details:

State 1: Extension payment $900; refund $1400.  (Tax withheld in 2017; no tax withheld for State 1 in 2018.)

State 2:  Extension payment $1,700; refund $5,540/  (Tax withheld in both 2017 and 2018).
