The correct size of the Specialized Tarmac SL8 road bike is 56, there is no doubt it is the correct size for her.
Size 54 is too small.
The 56 is perfect, for its height.
However, I see that the crotch size is low, if it is correct it could also take size 54 into consideration, adopting a stem 1 centimeter longer, in this way it will avoid having the saddle at handlebar height, which with size 56 it will surely happen.
But these are personal preferences.
Likewise it should be noted that the bike she just sold was a correct size for her.
So it would be better, perhaps to switch to a smaller size, even leaving the stem in the original size which is 100mm in size 54.
There is also the problem that you would like a racing set-up ... the one on the bike you just sold was fine ...
I think the best thing is to physically see the bike and try it out.
The biomechanically correct size is 56, but it would still feel bad, perhaps even worse than the previous bike.
Try the 54 with a 100mm mount and then see what changes to make.
Great racing bike!
