No, you cannot use TurboTax software to import realized gain/loss from investment income to calculate estimated taxes. But you can use our tax calculator to estimate your total tax liability. It is for 2023 but you can use it for estimate. Make sure to enter your long or short term gains so far and all other income and estimated withholding for the year. Once you have estimated balance due, you can use that to make estimated payments.

Also if your gains are long term, depending on your total income, tax rate will be 0%, 15% or 20%. Short term gain will be taxed at your regular tax rate.
