Well, LilyPond is doing exactly what you've asked it. Since
there is \new Staff both in the normal staff and in the tablature,
you get two new staves. You need to do \new Staff in the staff,
and \new TabStaff in the tablature. Furthermore, you need to adjust
alignAboveContext. To do that without repeating the music, you
can use tags.


\version "2.23.10"

ossia = { c''1 }

gtrOne = {
  d'1~ d'1
  \break

  <<
    { f'1 }
    \tag staff \new Staff = ossia \with { alignAboveContext = gtrOne } 
\ossia
    \tag ossia \new TabStaff \with { alignAboveContext = ossia } \ossia
  >>
  g'1
}


\score {
  <<
    \new Staff = "gtrOne" \keepWithTag staff \gtrOne
    \new TabStaff \keepWithTag ossia \gtrOne
  >>
}


See 
https://lilypond.org/doc/v2.23/Documentation/notation/different-editions-from-one-source#using-tags

Note that I've also removed your useless (empty) \layout block.

Best,
Jean
