Hey there, @thomas4.

I'd be happy to help you get on the right path to giving QuickBooks Online another try. Your research on the matter was correct, QuickBooks Online companies can only be imported from Desktop for the first 60 days after creation. The good news is, the support team can push that date out so the data can be converted. The limitation is in place as a safety net of sorts. In the common case that someone has multiple companies, selecting the wrong one by mistake when importing could result in the loss of year's worth of data, since everything is overwritten as you had expected. If the company you're trying to import into is older than 60 days, the data will be placed in a new trial company instead.

Now you'll have a couple options to move forward:

-Cancel the current subscription and switch it to the trial company with the data. These links will provide the steps necessary to cancel the subscription and then re-subscribe in the new company.

~OR~

-Contact the QuickBooks support team to extend the date so you can continue using the original company. They can also delete the trial company that was created by accident. You'll find their contact information at the link here.

After taking either route, you'll be back to business in no time. Please know if there's anything you need to succeed with QuickBooks Online this time around, I'll be here to help. Thank you for coming to the Community, have a wonderful rest of your day.
