A digital program is only a place to store the information that you must have got from elsewhere. Specify the original source, not your place where you will find your data.
No one can check them, no one knows where you've got your information and if it's correct.
If you do not know where the information originally come from, leave it unsourced, maybe write a research note into the biography, that the information is unreliable.
Good sources are primary sources, that means the information must have been recorded at the time of occurence (that means pre-1700!). Basically these are only church records, wills, legacy records.
But often there are secondary sources, they copied the information from primary sources. These can be books, Ancestry, MyHeritage, etc. But often these secondary sources also have its sources listed.
