Chromebooks open PDFs in the Gallery or Chrome viewer, which handles simple forms. Many school and government PDFs are built for Adobe Reader instead, so you see a blank page that says "Please wait... If this message is not eventually replaced" or the boxes simply do nothing.

Those files use a format called XFA that only desktop Acrobat reads. Many of them also carry a normal form underneath. Open the file at bettrpdf.com/fill: it drops the XFA layer, shows the regular form, and lets you type, sign with your touchpad or touchscreen, and download. If yours is XFA-only, you will see the same "Please wait" page here; ask the sender for a standard PDF, or fill it on any Windows or Mac computer with Adobe Reader.

Nothing is installed, it works on school-managed Chromebooks that block extensions, and downloading is free with no account. If the form is a scan with no boxes, click anywhere on the page to add text.
