If your monthly deposits are being made to a Traditional IRA
account, then the total contributed during the year would need to be entered
into your tax return as a Traditional IRA contribution.
Typically when deposits are made on a monthly basis, the contributions
would be designated for the tax year in which the deposit was made. This means that the amounts contributed from
January through April of 2018 would be designated for 2018, not 2017. You would not include those months as a 2017
contribution unless you specifically designated it for 2017 through the financial
institution receiving the deposits.
You may want to verify your total contribution amount by
contacting the financial institution so you can be sure it is entered properly
on your return.
