I do not advise you to file the return without the K-3 information unless you are certain it will be blank. The Foreign Taxes paid or accrued box being empty does not guarantee the K-3 will be blank.
If you have not filed the return and do not have key indicators to file your return without the K-3 I recommend filing for an extension and completing your return when you receive it. If you have already filed, you should wait until you receive the K-3 and then amend your return.
