State tax filing

This question relates to my future 2020 tax return. I received a $1500 rebate the year in Feb 2020 for a Nov. 2019 purchase of a plug-in, hybrid electric vehicle. When I phoned the California CVRP office (Clean Vehicle Rebate Program) I was informed that this rebate is not taxable as income in California and that they do not issue 1099's to the California FTB (Franchise Tax Board) or the Federal IRS. The lack of a 1099 income reporting form tells me that this rebate check does not have to be reported as income on my State or Federal tax return. I have been using Turbotax for my personal tax returns for over 20 years. Can some at Intuit please answer this question about the Federal taxability of this state rebate check? I look forward to feedback from Intuit. Thank you. Carmelo Amato
