UVA To Do List

So I’m starting on my to do list activities on the UVA guest account and when I click on the detail, it states that the fastest and safest way is to upload it through the SIS account. I/my parents need to sign form(s) so do I print out the paper and then sign and then scan and upload because on one of the forms, it says that it needs to be faxed OR mailed, but it says uploading through the account is safest?! I’m so confused!! Helpppp

My understanding is that anything that needs a signature needs to be signed on the paper document. You can fax it or mail it. We uploaded the W2s and the taxes (which had been physically signed).
