It's April 8. I filed yesterday and printed the return. Estimated Tax Vouchers still have the watermark DO NOT FILE FORM NOT FINAL.
Returns were accepted by the IRS almost immediately and tax due is scheduled to be withdrawn today, currently "pending" on my bank account.
What I've read in this thread is that this watermark issue had been resolved a month or two ago. But apparently not. Is my only recourse to pay online? I'm OK with that, just haven't done it before.
