I cannot add multiple 1099-SA’s. When I select the “Add” button, I either recieve an error that states “we hit a snag” or am prompted to change existing information.

Wondering if this is a software issue, have tried a few different browsers along with the mobile app with the same result. I have three to add and cannot seem to get more than one loaded in.

What is your filing status? You will only be able to enter multiple 1099-SA's if you are married filing jointly. 

If you are married filing jointly, you can try these things:

• Log Out Completely: Before doing anything else, click Sign Out in the TurboTax menu.
• Clear Cache and Cookies: This removes old, "corrupted" data that might be confusing the website.
• Use an Incognito (Private) Window: This is the most effective "quick fix" because it launches the browser without any saved history or extensions (like AdBlockers) that often interfere with tax forms.
• Check Pop-up Blockers: TurboTax often opens forms (like the 1099 PDF) or payment windows in a separate pop-up. Look at the right side of your address bar for a small icon with a "red X"—click it and select "Always allow pop-ups from Intuit."
• Restart the Browser: Close all open windows of your browser entirely and then reopen it.

Most TurboTax errors happen because the browser is trying to use an old "session" from a previous visit. By clearing the cache or using Incognito mode, you force the browser to establish a brand-new, secure connection with the Intuit servers.
