Send TextBox to 2 sheets

I have workbook with 17 sheets ..
I've build a userform
But when another sheet is active, the userform doesn't work ...
1- how to make it write and read from a specific sheet ??
2- at the same time , how to make TextBox1.Text to be saved at Sheet5 (A5) ?
3- How to set the ComboText data to read from specific sheet ?


Private Sub AddAndNew_Click()


Dim LastRow As Object

Set LastRow = Sheet1.Range("a65536").End(xlUp)

LastRow.Offset(1, 0).Value = TextBox1.Text
LastRow.Offset(1, 1).Value = TextBox2.Text
LastRow.Offset(1, 2).Value = TextBox3.Text
LastRow.Offset(1, 3).Value = TextBox4.Text
LastRow.Offset(1, 4).Value = TextBox5.Text
LastRow.Offset(1, 5).Value = TextBox6.Text
LastRow.Offset(1, 6).Value = TextBox7.Text
LastRow.Offset(1, 7).Value = TextBox8.Text
LastRow.Offset(1, 8).Value = ComboBox9.Text
LastRow.Offset(1, 9).Value = TextBox10.Text
LastRow.Offset(1, 10).Value = TextBox11.Text
LastRow.Offset(1, 11).Value = TextBox12.Text
LastRow.Offset(1, 12).Value = TextBox13.Text
LastRow.Offset(1, 13).Value = TextBox14.Text
LastRow.Offset(1, 14).Value = TextBox15.Text
LastRow.Offset(1, 15).Value = TextBox16.Text
LastRow.Offset(1, 16).Value = TextBox17.Text
LastRow.Offset(1, 17).Value = ComboBox18.Text
LastRow.Offset(1, 18).Value = TextBox19.Text
LastRow.Offset(1, 19).Value = TextBox20.Text
LastRow.Offset(1, 20).Value = ComboBox21.Text
LastRow.Offset(1, 21).Value = TextBox22.Text
LastRow.Offset(1, 22).Value = TextBox23.Text
LastRow.Offset(1, 23).Value = TextBox24.Text
LastRow.Offset(1, 24).Value = TextBox25.Text
LastRow.Offset(1, 25).Value = TextBox26.Text


MsgBox "One record written to Contacts Information"

response = MsgBox("Do you want to enter another record?", _
vbYesNo)

If response = vbYes Then
TextBox1.Text = ""
TextBox2.Text = ""
TextBox3.Text = ""
TextBox4.Text = ""
TextBox5.Text = ""
TextBox6.Text = ""
TextBox7.Text = ""
TextBox8.Text = ""
ComboBox9.Text = ""
TextBox10.Text = ""
TextBox11.Text = ""
TextBox12.Text = ""
TextBox13.Text = ""
TextBox14.Text = ""
TextBox15.Text = ""
TextBox16.Text = ""
TextBox17.Text = ""
ComboBox18.Text = ""
TextBox19.Text = ""
TextBox20.Text = ""
ComboBox21.Text = ""
TextBox22.Text = ""
TextBox23.Text = ""
TextBox24.Text = ""
TextBox25.Text = ""
TextBox26.Text = ""

TextBox1.SetFocus
