Preparing tax returns in Lacerte often means working through several diagnostic messages. These alerts help you spot missing entries, inconsistencies, or requirements that must be addressed before you can file. When you have dozens of forms and schedules open, finding the exact reason behind a diagnostic can feel time-consuming.

The “Find My Diagnostic” Center simplifies this process. Instead of manually searching through help articles, you can enter the diagnostic number and instantly view the explanation, instructions, and any steps to clear the issue.

This guide walks you through how the tool works and how you can use it to resolve diagnostics faster and move your returns forward with confidence.

What is a Lacerte Diagnostic?

A Lacerte diagnostic is an alert generated by your Lacerte Tax software to help you review your return before transmitting it electronically. These diagnostics highlight errors, missing information, or important reminders that need your attention. You can view them directly in the Diagnostics tab, and each item includes a reference number that appears right after the diagnostic message.

To use the “Find My Diagnostic Center” for Intuit Lacerte, you must access the specific tool on the Intuit support website and enter the exact diagnostic number provided by your Lacerte software.
