Oh, there's something else first. You mentioned a deceased mother. "Whose" return is the 2017 return--is that yours? And "whose" return is the 2018 return in that account? And did the 2017 data flow into your 2018 return in that account when you started the 2018 return? i.e., did "your" 2017 data transfer into "your" 2018 return, or did "your" info transfer into your mother's 2018 return?
Be aware that you can only prepare one 2018 return in that account. If you prepare your mother's return in that account, then you'll need to use a new account for you, or vice versa. Since it's "your" account, it will mess up your own account continuity if you prepare the mother's return in it.
