Can I be forced to sell a home left to me and one other sibling in a will

Most likely.  Unless it was left to you as joint tenants with rights of survivorship, your sibling can force a sale through a partition action.  And such a sale is like a foreclosure sale so usually one of the interested parties--the one with the biggest checkbook--gets to buy the property at a bargain price, with the other sibling getting part of the sale price.  It is far better in this situation if the siblings can work out a deal, like you buying out your sibling's interest at fair value or paying half the fair market rent to your sibling, or selling the property through a realtor to get the maximum value out of it.
