Hello lisa276,

Welcome to the QuickBooks Community. I'll be happy to share more info so you're on the right track with your work. QuickBooks is a versatile program that enables you to keep track of your income and expenses with ease.

In order to successfully edit your Chart of Accounts, I encourage you to check out the helpful resources below: 

• Edit the Chart of Accounts
• Change the type of an existing parent account or subaccount in QuickBooks Online

I encourage you to check out the articles and let me know if you have additional questions. I'll be one message away in case you need anything else. 

Yes, I believe you can change the account type without issue.  

Note: If you do try to change it from AR to Other Current Asset and you get an error message pop-up window then perhaps you'll need to get a bit more hands-on help from QB.
