You characterize the amount of the original contribution, not the earnings or losses. If the contribution was $3,000 then that is the amount of the recharacterization. The earnings are accounted for o a 1099-R form and your explanations statement for the recharactorization. The is no change in the tax or IRA basis.
No need to amend a do-nothing amended return. If the IRS questions it (doubtful) just answer their letter with the facts - easier than amending.
