I qualified for disability student loan forgiveness in 2016 with monitoring ending 2019. The new tax plan says it's not considered taxable income. Will I owe taxes?

Since I'd receive a 1099 in 2019 when the 3 year monitoring period is over, is that the year my loans are considered discharged and would my loans apply for the Stop Taxing Disability and Death policy? The student loan company couldn't tell me, and I'm unsure who to ask to make sure that my loans aren't going to be considered taxable income.
