Capital Gains on house sale - minimum estimated tax to avoid penalty

Federal tax salary withholdings this year will be $30K (let's call it) and are ~85% of tax due for '24.

Taxable gain on sale (above the exclusion) is ~$300K.

For right now, what's the minimum supplemental estimate payment I need to pay to eliminate penalty interest risk? Is it as low as something that gets my tax payments / witholdings this year comfortably above the $35.2K ($30K/.85) from '24? So maybe $10K?
