Welcome to the Community, @MO78.
Currently, the option to add the total deposit field on the estimate template is unavailable in QuickBooks Desktop (QBDT). In the meantime, you can continue entering the words in the template as a workaround.
I can see how this option would be helpful for you, and I'll take note of this. Our Product Engineers are always looking for ideas to consider on how to improve QuickBooks.
I also recommend visiting our Blog site. This is where we share recent happenings and future developments, such as updates to newly added features. Here's the link: https://www.firmofthefuture.com/product-industry-news/product-updates/.

Reach out to me in the comment section below if you have any other questions or concerns. I'll be happy to help. Have a good one!
