Deductions & credits

Same problem, only worse — I do see 2017 on my iPhone, but not on wife’s (signed into my account. I verified the account ID on both. In a separate but possibly related issue, I also found out I can’t merge two ID’s. In yet another separate issue, I don’t know if I can access an old account with current Intuit 1sizeFitsAll login ID. Any help on these two other questions/issues?
