Correct. Prior to the Tax Cuts and Jobs Act of 2017 you could claim a deduction subject to the 2% of AGI floor for the unrecoverable basis, but the TCJA suspends until 2026 deductions subject to the 2% of AGI floor.
Since it's not clear that your basis remains for future use if you make a complete distribution of your entire traditional IRA balance, I suggest leaving a small balance in your traditional IRAs to ensure that the basis carries forward to be able to be applied to future traditional IRA distributions.
