Hi! I found a way to do it after trying many ways.
If you want to enter different E-S amounts for your 2023 (next year) Federal Tax return, go to the upper screen folder tab labelled "FEDERAL TAXES" (the 2nd topic "tab" from left, after "PERSONAL INCOME" folder tab) and on this topic, click on the 3rd "bubble" or topic from the left, labelled "Other Tax Situations". Once in this section, select the topic "Form W-4 and Estimated Taxes". Once there, it will ask you "Do you want to change your W-4 withholding for 2023 [or the next year]?" Say YES (even if you DON'T expect changes in your W-4!!) - and this will take you to a window to enter your estimated income for 2023 (or the next year)- for any income type besides W-4. If you know how much more (or less) you will earn the next year that will result in the extra/lesser income than the current tax year, enter those ADDITIONAL (or SMALLER) $ you expect the following year. This will change your E-S payments to accommodate your greater or lesser income you expect.
For STATE E-S taxes changes, go to the top screen folder tab "STATE TAXES" (beside the "FEDERAL TAXES" mentioned above, and on the Menu here, scroll down to the section "Other Situations", which you will see describes "estimated taxes for next year". Click here and there you will be able to change the TurboTax default estimates of your E-S taxes for 2023 (or your next tax year).
Hope this helps. These 2 procedures worked for me.
