There are two ways to sign a 8332 form.
1) Sign part I for the current year only. That 8332 is only good for the one year.
2) Sign part II that releases for future years as specified.
If you signed part I then there is nothing you need to do.
If you signed part II then you need to file a new 8332 part III that reascends part II, but that that will not take effect for the current year.
See the 8332 instructions:
