I owe tax in 2019. Working on 2020 tax estimates. No place in TurboTax to show planned tax to be withheld from Soc Security for 2020. Can I input the planned amounts in the "2020 deduction section"? Need to show IRS I am already paying additional tax for 2020 in addition to any quarterly amounts. There is no other place that allows me to account for changes to W-4s for Social Security.
