Tried again on multiple browsers and cleared cache - still same error. "

This should not have happened. Don't worry - your data has been saved.

Our TurboTax application has stopped working properly. It rarely happens; we're sorry it happened when you were using it.

Maybe the puppy helps, but you're probably mad and we're already hard at work fixing it.

Please check back again soon. We should resolve this quickly.

You can also contact our support team at https://support.turbotax.intuit.ca/contact/

Thanks for your patience,

"This wasn't expected, but we're working on fixing it"
