Hi, @skyej944. Thanks for reaching out to us here in the Community.

I know how essential it is for you and your business to create an estimate. Since you've encountered that the link for estimates is not working, it might be that your account is still in an old experience in QuickBooks. 

For now, our product experts are currently in the process of enhancing the new estimate feature in QuickBooks. Thus, this rollout update will gradually change into your QuickBooks Online (QBO) account. 

To see which experience you have, here's how:

1. Select + New. 
2. Select Invoice or Estimate. 
3. If "New" is displayed next to the form's title, you are now using the new experience.

Here's an image for your reference.

For more detailed information about the new updates in estimates and invoices in QBO, you can click on this link: See what's new with estimates and invoices in QBO.
