Illinois State Tax form ICR error 2018

I am furious that after using this product for over 20 years without issue because of the integrity of the product that I get a notice from the State of Illinois that my returns are wrong because of the Real Estate Taxes.  After reviewing this, the turbotax autocaluation on the ICR Form entered the RE taxes multiple times, throwing the credit calculation off. 

 

WHO is suppose to check these calculations BEFORE you roll your product out???? What recourse do I have with Turbo tax.  Fuming that I have to correct the error manually and resend the documents!! Thanks Turbo Tax
