I've looked at two clients for 2018 and both had this problem.  Both had itemized deductions on their 2017 returns and chose state income tax for the state tax deduction. Both got state refunds from 2017 in 2018.  On the 2018 returns, the state tax refund work sheets (with transferred information for 2017) mark them as having claimed the state sales tax as the state tax deduction.  This results in no taxable income from the 1099-G, which looks to be wrong.

Am I missing something or was/ is there a problem with transfering the state tax info from 2017 into 2018?
