Performing Two Sajda-e-Sehaw
These application matters are ijtihadi in nature as there can be endless possibilities in this regard. One has to decide for himself /herself that which course of action requires a sajda-e-sehaw genuinely. It is an individual decision, and if done with all sincerity, then there won’t be any burden on the person Insha’Allah. Performance of single Sajda-e-Sehaw, in my opinion, would compensate for all the mistakes or doubts one was having, including those one came to know after some time. Even if a long time passes, Sajda-e-Sehaw can still be done and there’s no need to repeat the Prayer. Please refer to the following portion of Ghamidi Sahab’s book Meezan where all narrations regarding Sajda-e-Sahaw have been collected in one place and from these narrations, you’ll be able to see the application of Sajda-e-Sehaw principle with much clarity. https://www.javedahmedghamidi.org/#!/mizan/5aa6a4315e891e8f44a45788?chapterNo=4&subChapterNo=0&subChsecNo=9&lang=en
