Retirement tax questions

1040 Line 5a and 5b had the correct amounts.  AR 1000F line 18 had the correct gross distribution but put the same amount for taxable amount.  Then it took off the $6000 exemption. 

 

It doesn't make a lot of difference in the tax, but I am unwilling to e-file a return with the wrong numbers.  I have had this problem before and had to send Arkansas a paper return so that I could force it to be correct.  I input the 1099R with 2a left blank and checked the Employer-sponsored pension box.  One year I found the incorrect taxable amount on some TT worksheet buried in the federal return, but the actual federal return was OK and only the state return was wrong.  I haven't found if that is the case this year, so will try to check this again.
