Yes, it is fine to increase withholding on your spouse's pay rather than making quarterly estimated payments (as long as you'll be filing a joint return, of course.)
I would suggest that you make a note on your calendar to check to see where you are with the withholding around mid-year so that you can make any additional adjustments, if necessary. A great place to do this is our W-4 Calculator. If you make the changes this time of year (or any time after around March) you should do an additional check around October of this year and then consider a reset in January. The reset in January is because a change made after the first few weeks of the year will often try to "make up" for the missed months so you could end up over withholding.
TurboTax can print the 1040-ES vouchers for you, but many taxpayers do find it easier to just pay online. If you do pay online, you do not also need to mail in any voucher. Just be sure to note that the payment is for "estimated 2025 taxes" so that they are credited properly.
