So someone must have acted as administrator to change house ownership into the 6 of you and distribute all monies. That person might be the first person to talk to.
What do you want? Do you want to sell and get your 1/6 value or do you want to continue to own the 1/6th?
If you want to sell, the easiest thing might be to ask one of your 5 siblings to buy you out. The person who administered the estate should know the value of the house. Then walk away with your 1/6th.
The next option might be to have a family meeting where the 6 of you decide what you want to do? Ye may want to do 6 different things which is why selling your 6th to one of your siblings might be a fast and smart move.
If you do decide to co-own the house then be sure to pay 1/6 of the costs of upkeep and repairs, heat, water, electricity, property tax etc., and ensure the 3 siblings pay rent to the other three, ensure lease is in place, taxes are paid, all the usual landlord tenant stuff.
A final option is to gift your 1/6 to the three living at home. Or any other sibling. Are any of them under 18 or in full time education, would they have special needs that need protecting?
A family meeting to air any or all these issues may reveal what the elephant in the room is as mf1 says.
