Looks like a BUG in TurboTax software with respect to 2018 tax year filing...At the time of my 2018 tax year filing the ITIN was active and I have used ITIN for many years. I became permanent resident in 2015 and continued using only ITIN for tax filing years 2016, 2017.... Later due to TCJA in 2018 looks like taxpayer should claim CTC only using SSN...turbo tax hasn’t given any hint or message that claiming with ITIN was disallowed for CTC in 2018 and tax payers are supposed to use SSN.
Due to this I lost getting my refund from IRS and also paid about 525 back to IRS!!!!!
