Hi @thedashin,
Your question involves a QuickBooks Desktop (QBDT) company, while the tag on your post is QuickBooks Online (QBO). I'm going to assume what you want to do is convert your QBDT company to QBO.
The first thing you need to do is ensure you have the latest version of QBDT installed. If necessary, you can also decrease the file size of your company file before the conversion process.
A detailed guide on how you can convert a QBDT company file to QBO is in this article: Move your QuickBooks Desktop file to QuickBooks Online. It even includes a short video that you can use as a reference for the process.
Lastly, I'll leave this article right here: What to expect when you switch from QuickBooks Desktop to QuickBooks Online. It's a list of data types you have in QBDT, and what to expect when you convert them to QBO.
In case you're referring to a different scenario, I'd love to hear more from you. Place a comment below, and I'll be sure to get back to you.
