Please, tell me the difference between these sentences

Could anyone tell me the difference between the following two sentences?
1.- What is there to do? (Maybe, this question is related to an answer like this: There are potatoes and chicken, do what you wish)
2.- What do I have to do? (You have to prepare chicken with potatoes)

But what about these?
1.- What is there to say?
2.- What do I have to say?
In this case, the difference is not so clear to me.

Thank you in advance!

CalifJim, could you help with an Spanish translation?

Eladio,

I don't think you need a translation! The first of each pair is impersonal, the second has "I". It's like the difference between "hay que hacer ..." and "tengo que hacer ...", only in question form.

You may be bothered by the somewhat idiomatic meaning of "What is there to say?", i.e., "There is nothing to say", "There is nothing to be said", "There is nothing one can say". This borders on "No hay remedio".

Jim

I'll make slightly different answers, if I may!

1.- What is there to do? - Well, I've already peeled the potatoes, you can put the chicken into the oven, if you want.

2.- What do I have to do? - We have divided the chores among us: You peel the potatoes and do the washing.
