Okay.

Firstly, we know that Ingrid never did come to the LWM through the First Curse and later in 2001 she entered Storybrooke using the Scroll. She adopted "Sarah Fisher" as her alias, something she did herself and not caused by the Curse.

Secondly, when Pan cast the Curse, Regina mentions that she had to pay the price to undo it, one was that she can NEVER see Henry again and another was EVERYONE not born in the LWM would return to their respective worlds. Emma was an exception as she was born to escape the Curse (a reference from the time Emma was born in the EF to escape the First Curse). So, the Snow Queen would have not been able to leave Storybrooke even if she wanted too. If she could have done it, then Neal would have followed too. Since Emma and Henry would have forgotten everything in Storybrooke and Regina altered their memories, she could have altered Neal's one too to fit them 3 as a family, but Neal is prohibited from leaving.

Thirdly, when everyone returned, it can be assumed that the Snow Queen returned as she still remains the owner of Any Given Sundae as the Second Curse reverted everything following Pan's Curse and back to before Regina undid the Curse. Since Sarah Fisher was never her Curse name, it was never listed it the book of records and it's probably listed as Ingrid since the second Curse did not create new counterparts.
