Please how do i retrieve my saved Estimate.

Thanks for visiting the Community, @usertokunbo4u. 

We can use the audit log to check activities involving that specific estimate. Here's how:

1. Go to the Gear icon, then click Audit Log.
2. Click the arrow down next to Filter, then choose All Users and set the Date.
3. Move the radio button to Show only these events.
4. Mark the Statement box.
5. Click Apply.

Just in case you're unable to find the estimate, I'd recommend you recreate it. 

You can also read through this article for your future reference: Convert your estimates into an invoice. It helps you learn about how to turn an estimate into an invoice after a customer accepts it.
