Whatever you are doing now cannot be done on your phone. It is no longer possible to use online TurboTax. Online tax preparation and e-filing are now permanently closed until the 2019 tax filing season opens. You need to use desktop software which must be downloaded to a full PC or Mac—not to a mobile device. It is not clear from your post whether you are trying to work on an original 2018 return, or if you need to make corrections to a 2018 return you already e-filed.
