To the poster that calls himself Helpful:
I believe your point was that Rashi by definition had to have the correct girsa in Seder Olam, and that it was authoritative. As I and others have pointed out (as well as Tosfos), there are multiple contradictory Medrashim regarding the question. Saying that Rashi’s version was not authoritative and makes less sense than the other Medrashim (such as the one that says she was 14) is a valid Shittas Rishonim (such as the Tos. Yeshanim on the Daf), and is not C”V due to the Tos. Yeshanim having “20th century sensibilities”.
If that is not what you were refering to with your comment, then I apologize.

P.S. I’m not saying there are no answers to Pashut Pshat in Rashi, either.
