If your parent is in the shipping business, you can wrap things up for them and get the addresses ready.

If your parent is in the bulk mailing business, you can stuff envelopes and put addresses on the envelopes as needed. This is something that many types of home business, bulk mailings and other businesses do all the time for sales.

Maybe your parent is a work at home assembly worker, or similar type business worker. You can help doing what they are doing to increase their business and their quota while making money.

You can do the filing, put papers in order, and make copies or print outs as needed if your parents work from home, or if they have lots of work that they bring home to do.

You are not limited to just working for your parents doing these office and administrative jobs. If your neighbors, siblings, or other people you know work from home you could be working for them and sharpening your skills doing office work and odd jobs. It might just be answering the phones is what is needed, but you can do that too!
