This does not directly address your question, but it just occurred to me that your IRA contributions might print out on your instruction page. When you e-file you have the option to download or print your return, and the first page is a page of instructions. Usually it just summarizes your return and your expected refund and confirms e-filing. In your case, I wonder in the instruction page will include something like "Don't forget to make your IRA contributions of $x,xxx before April 18." I don't use this feature so I can't test it myself.
