I'm here to offer my assistance so you're able to correct your 1099 form in QuickBooks Online.
As an initial troubleshooting step I recommend clearing the browser cache. The cache is in place to collect frequently used data to make loading web pages quicker and easier. If it becomes too full it can potentially cause certain viewing and performance errors. Clearing the cache will remove anything that's preventing the page to load properly. Here's how to get this done in Chrome for example:
1. At the top right, click More (three vertical dots).
2. Click More tools and then Clear browsing data.
3. At the top, choose a time range. To delete everything, select All time.
4. Check the boxes next to "Cookies and other site data" and "Cached images and files."
5. Click Clear data.

Please give this a try and let me know if you're able to make the corrections afterward. The Community always has your back if you have any other questions.
